宁夏引黄灌区低洼盐碱荒地的开发利用方向研究

宁夏自治区引黄灌区有十几万ｈｍ２的低洼盐碱荒地资源,长期处于荒芜状态。本文试图通过对资源条件进行综合评价及对各种开发利用模式综合比较,提出目前最佳的利用方向是挖塘养鱼造台田,建立立体生态农业体系。这对于当地农村经济发展和西北地区渔业基地建设具有重大意义。

A STUDY ON THE DEVELOPMENT AND UTILIZATION DIRECTION OF THE LOW-LYING SALINE-ALKALI WASTELAND IN THE YELLOW RIVER IRRIGATION REGION IN NINGXIA

There are more than one hundred thousand hectares of low-lying saline-alkali wasteland which remain unused for a long time in Ningxia. Through integrated evahiation of local resources conditions and comprehensive comparison of different developing-utilizing models,this paper suggests that the best way to exploit the wasteland is to set up a stereoecoagricultural system by digging pools to breed fish and constructing tableland for cultivation. This system will be helpful to the development of rural economy and the estabhshment of fishery bases in Northwest China.
