Based On The Background Of Decreasing Water Resources Inner Mongolia West Liaohe Plain Agricultural Sustainable Development Research

Inner Mongolia west liaohe plain is located in northeast plain to the Inner Mongolia plateau transition zone, climate has obvious transitional. West liaohe plain is important grain production base in Inner Mongolia autonomous region,and its agricultural production has obvious difference with Inner Mongolia hetao plain and TuMoTe plains.the area of agricultural production mainly depends on groundwater. In recent years, global warming lead to temperature rise, precipitation reduced markedly and for surface water and groundwater recharge reduced. The watdr of agricultural production increases.Therefore, based on regional water resources rationally adjust the agricultural production, and to realize agricultural sustainable development have the important meaning.This article chooses the typical agriculture of Inner Mongolia west liaohe plain-Horqin Left Middle Banner for research object.Mainly from the local groundwater, climatic conditions, agricultural input and output, market factors and policy on agricultural structure adjustment, and analyses the agricultural development present situation.In the background of decreasing water resources, evaluate the agricultural production status quo. At present, Inner Mongolia west liaohe plain agricultural production exist the following problems:agricultural planting structure unreasonable, water resources utilization rate is low and waste is serious. And then using the correlation coefficient method calculated the influence degree of precipitation, different crops types,different irrigation area with the groundwater in the plains.Again through the main crops important performance, stable performance and drought resistance performance evaluation. Finally, on the basis of existing water resources in Inner Mongolia west liaohe plain, the paper puts forward Suggestions on Agricultural sustainable development:first, based on water resources adjusting agricultural planting structure, choose drought-resistant crops varieties, reduce water usage number of crop planting area, increasing drought resistance properties of strong, stable sown area of sexual high crop; Second, Suited to the local conditions to the development of agriculture. In terrain flat, soil fertility good location increasing maize seeding area, ShaTuo land can be appropriately planting soybeans, In salt and low-lying expand rice planting area; Third, Based on the water, with maximum profit as a target in developing agricultural production; Fourth, taking the market as the guidance to develop higher agricultural commercialization. Through in the background of water resources reduction, researching Inner Mongolia west liaohe plain agricultural, hope to make the contribution for he plain agricultural sustainable development...
