区域水土资源平衡与灌溉优化模型研究——以陕西关中灌区为例

REGIONAL WATER AND SOIL RESOURCES BALANCE & OPTIMIZING MODEL RESEARCH ——Taking Guanzhong Irrigation Region in Shaanxi as an Example

区域水土资源的潜力开发利用是提高水土资源利用效率 ,提高效益 ,促进农业经济发展的重要途径 ,其方法过程首先考虑水资源与土地资源的组合与匹配 ,并根据作物发育过程对水土资源的需求规律 ,进行优化模型的建立是水土资源开发建立在科学基础上。本文根据这一思想 ,对陕西关中灌区进行了试验研究 ,建立主要作物在不同灌区的优化模型。

The potential development and utilization of regional water and soil resource is an important way to raise uasage efficiency of resources,output results and promote the development of agricultural economy.About which,the orgainzation and combination of water soil resources should be considered firstly.Then,to set up optmizing model according to crops' demand to water soil resources in the course of growing.In this way,the development of water soul resources is based on quantitative methods. Following these above,the paper makes exprimental research to Granzhong irrigation region and sets up optimizing models of main crops in different irrigation regions.
