On 25/04/2015, in Economics papers, by rain

In order to research change of water resources in Kashgar Region and analyze the influence of the driving mechanism, such as natural environment and economy, the paper, based on the remote sensing data of around1990,2000and2010,36maps in total, categorizes water resources into two groups:planar water(water body, lake, glacier) and linear water(river system, man-made trench). With the method of visual interpretation and Computer interpretation, the area of planar water and the length of linear water were calculated, separately. Additionally, concerning the corresponding local climate and economy data, statistical results form those data indicate that the area of water body, lake and glaciers has decreased by92km2,152km2and875km2, respectively, and the length of river system experienced a loss of421km, whereas the length of man-made trench has increased by528km. In recent two decades, a phenomenon named “warm and wet transition” occurred, whose specific performances, in this paper, are that the average annual temperature has significantly grown0.048℃per year, and the annual precipitation by1.5mm/10a.The analyze_indicates that increasing glacier melting because of increasing temperature in summer, however, water resources in winter began to decrease. While at the same time, increasing temperature in Kashgar Region induces shriveling stores of glacier. And the precipitation, during this time, keeps increasing in a low ratio and thus can not increase water resources in Kashgar Region in a large margin. Furthermore, economy dates show that demand for water has obviously risen owning to the rapid increase of population and GDP, which are also the important factors resulting in decreasing trend of surface water.

On 24/04/2015, in Economics papers, by rain

Water is becoming one of the most and valuable resources in modern society.Sustainable utilization of water resources is an important basis for the sustainabledevelopment of Social-Economic system. The efficiency of water utilization inGuangzhou city is very low in the past several decades. Recently, with thedevelopment of economy and the increase of population, water pollution inGuangzhou city is becoming more and more seriously. Water shortage is becoming alimiting factor for the sustainable development.In this thesis, theories of system dynamics and sustainable development wereused to study the sustainable utilization of water resources in Guangzhou city. Mainconclusions based on our research are as follow:1. By using the tool of system dynamic analysis–STELLA software, systemdynamics model for water resources in Guangzhou city was established. The model isbased on analysis of water resources system in Guangzhou city. Comparisons of mainindices between simulated values and actual data indicate that simulated values agreewith the actual data well during 2000-2005, which verify the validity of the model.2. Under current trends, water demands during 2006-2025 in Guangzhou citywere forecasted by the model simulation. Result shows that water demand inGuangzhou city will increase in the future 10 years, and the maximum water demand1.1437×1010 m3 will occur in the year 2018. Factors affecting water demand and watersupply were also simulated. Results showed that recycle ratio of water for industryand irrigation coefficient of agriculture remarkably influences water demand. Modelsimulation results indicate that water consumption of industry will reduce 5×108 m3when recycle ratio of water for industry increase 0.5% per year. Water consumption ofagricultural irrigation will reduce 2×108~3×108 m3 when irrigation coefficient ofagriculture increases 1% per year. The model simulations show that reclaim waterwould increase every year under the trend of increasing treatment rate of sewage inGuangzhou city, and reclaimed water available will reach to 6×108~9×108 m3. Withthe current trend of development and utilization, the carrying capacity of water resources for population will increase slightly during 2006-2025, reaching 16.6million people in 2025. However, the increasing rate will decrease.3. There are many researches on index system for sustainable utilization of waterresources in arid regions. However, few researches concerns about index system in therainy region. We attempt to build an index system for sustainable utilization of waterresources in Guangzhou. The index system can be applied to other rainy regions.Index of sustainability of water resources utilization in Guangzhou city was conductedusing AHP (analytic hierarchy process) approach. Results indicated that index ofwater resources sustainable utilization increased in Guangzhou city during 2000-2005.The index of sustainability in 2005 reached 0.518, which is 36.32% increase ascompared with that in 2000.4. In order to estimate the sustainability of water resources utilization underdifferent political strategies, Scenario analysis was performed, and fivescenarios–strategy of no change, reclaimed water reuse, saving society, waterprotection and harmonization–were assumed. Results show that index of waterresources sustainable utilization under strategy of harmonization is the highest of allthe assumed strategies. Index of water resources sustainable utilization underharmonization strategy will increase to 0.727 in 2025, which is 1.4 times of that in2005.

Shanxi lacks of water resources for that it ranks the 29th place in per capita and per hectare water resources list of 31 provinces/ municipalities of China. With development of national economy and society, population increase and city establishment will speed up so that water consumption in industry and city life and ecological construction will greatly increase, which makes water shortage in Shanxi worse. One of key solutions to Shanxi water shortage is to save water, especially in Shanxi agriculture because Agricultural irrigation consumes enormously water. Researches and extension of Agricultural water saving techniques will ensure realization of sustainable water consumption, and will play a important role in improvement of crop production, ensurence of national food security, and increase of farmers’income, and will improve sustainable development of economy and society, and of new socialistic rural areas.Based on procedures of systematic analysis, qualitative and quantitative analysis, and inductive and deductive methods, the present paper reviewed worldwide Agricultural water saving researches, evaluated water consumption statuses in Shanxi, and examined Shanxi agricultural water savings. Further, three non- Engineering water saving techniques were put forward to be applied in Shanxi. These 3 key techniques were analyzed with aspect to water saving and crop improving effects, and will serve as guidelines to agricultural water saving activities in Shanxi.Main conclusions are as follows:(1) Non- Engineering techniques are one of important components of agricultural water saving technology. These techniques are internally able to reduce water uses. They are involved in water saving in crop itself, temporal and spatial layout of crops, and farmland, therefore, are key factors for sustainable action of water saving irrigation engineering.(2) Non- engineering techniques proves to be suitable for current Economic conditions in Shanxi for they require low Investment, instant effects, are easy for farmers to accept and master, and to be applied and extended into large rural area. They are more important in range rainfed agriculture and limited irrigation agriculture. (3) Three agricultural non- engineering techniques were brought forward, namely, agronomic water saving, biological water saving, and managing water saving. Their effects of water saving and crop yield increasing were analyzed in terms of water production rate and water utilization rate.

On 29/08/2013, in Economics papers, by rain

The Yellow River’s Comprehensive Treatment has always been as a major event inChina.The Yellow River meanders through many parts of China. It not only moist the soil ofChinese nation, but also brings a lot of disasters in history. The severely imbalance of flow,with too much sediment in Yellow River is rarely seen in other rivers. The comprehensivetreatment requires high-tech, to improve and to combine the traditional experience of the flowand sediment ratio in its every basin.Even in today’s opinion, many treatments in the history of the Yellow River are relativelyvery scientific. But as a result of the political and Economic conditions in that time, theunderstanding of Yellow River before is deficient. The lack of technical and many otherreasons result in the fail in putting the theories into practice or fully met. It is proved that as along river, the Yellow, absolutely can be treated in many sub-basin first; However, themulti-sediment, as a major feature of the Yellow River, which requires not just the normaltreatment of other rivers.Yellow River is constantly changing, which requires the combination of hydrology,climate, geology and other factors, the detection and managing of technique Engineering,furthermore, the technology upgrade. So that can finally achieve the comprehensive treatmentof scientific flood control, ice flood control, water resources reasonable proportion andmaking use of sediment resources, etc.Science and Technology is continually developed along with the changing of YellowRiver. The proposal of many new scientific theories, independent research and developmentof high-tech, these innovations will bring us a new beginning for the comprehensive treatmentof the Yellow River.
