A Study on Water Saving Non-Engineering Techniques in Agriculture in Shanxi

On 11/04/2015, in Economics papers, by rain

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.

On Water Management Since Qing Dynasty

On 09/07/2012, in International, by rain

【Abstract】 Water is one of the Basic materials in human existence and the development of society and economy. Its Management has been an eternal subject for the Management of human society. In such an Agricultural country like China, How to take advantage of it has been a big event. And its Management has played a Basic role in the process of Social and historical development and will develop together with the advance of society, politics and Economics.In Qing dynasty, the last of the feudal society, great river disasters often happened successively because of the corrupted feudal rule and the low productivity. During this time, water management intended to solve the problems of human existence and was focused on disaster tackling, irrigation and water conservancy, with the invasion of western capitalism. The Chinese society fell step by step into a semi-colonial and semi-feudal one. In about a century, the suffering Chinese were seeking for ways out. They began to learn from the west and introduced advanced water management and science and technology. As a result, they established modern water conservancy. Then the People’s Republic of China was founded and a big socialist country stood in the east of the world. After more than 50 years development, we have established the socialist market economy and water management has experienced the transit of Engineering management to resource management. It is reasonable to draw such a conclusion that the changes in the Chinese society brought great changes to water management, which, in turn, embodies the Social changes and reflects from a special aspect the process of the Social changes.This dissertation analyzes the content of water management and the factors that influence it. It attempts to reach a conclusion about the changes in water management from the Qing Dynasty to the present society and reveals the interactive relationship between water management and the development of politics and Economics. It also aims to discuss, in practice, the patterns of water management under the socialist market Economic system and in theory, how to build a water -saving society, with this as the purpose, the author of this dissertation attempts to provide some suggestions on the policies about how to build a water saving society.
