黄土高原半干旱区雨水利用与可持续农业发展研究

黄土高原半干旱区是一个特定的生态类型和重要的农业区域 ,严重的水土流失和频繁的干旱是该区农业可持续发展的主要制约因素。本文在分析雨水利用可行性的基础上 ,提出了农业发展的有效模式———集水型生态农业 ,它不仅适应于当地的雨水等自然资源条件 ,更适应生产力发展水平 ,易于在农户水平上推广 ,并且具有显著的经济、生态和社会效益 ,是实现该区农业可持续发展的战略性举措 ,同时也为“退耕还林 (草 )”开发战略的实施提供了一个思路

STUDY ON RAINWATER UTILIZATION AND AGRICULTURAL SUSTAINABLE DEVELOPMENT IN SEMI- ARID REGION OF LOESS PLATEAU

The Loess Plateau semi-arid region is a specific ecological type and important agricultural zone, severe water and soil loss and frequent drought are two major factors in restricting the agricultural sustainable development. This paper, on the basis of analyzing the feasibility of rainwater utilization, puts forward the water-collecting eco-agriculture, which is a effective model for agricultural development and suits not only the natural resources, especially rainwater feature, but also the level of productive forces. And it is easy to spread on the household level and has significant economic, ecological and social benefits, and is an strategic move to realize the agricultural sustainable development in this region and provides a thinking for the strategy of "reverting the land to forest (grass)".
