黄河下游引黄灌区农业生态环境脆弱性评价及对策

 对黄河下游引黄灌区的水资源条件、发展现状、及存在的问题进行了剖析,提出了农业可持续发展受到脆弱生态环境影响的主要因素,其中包括自然因素和人为因素等。在此基础上,建立了引黄灌区农业脆弱生态环境评价指标体系,研究了农业生态环境脆弱度计算方法,对黄河下游农业生态脆弱度进行了计算。依据计算结果对农业脆弱特征进行了评价,并提出了改善黄河下游农业生态环境的合理性对策。

Evaluation and Countermeasures of Agricultural Eco-environment Frangibility in the Irrigation Districts of the Downstream of Yellow River

The water resources, irrigation development status and the problems in ecological amiable development of the irrigation districts in the downstream Yellow River were analyzed. The main natural and contrived factors which affect agricultural sustainable development were put forward. Based on the results above, the evaluation index system of irrigated agricultural eco-environment frangibility was set up. The calculation method of agricultural eco-environment frangibility was studied, which was used for calculation on agricultural eco-environment frangibility in the downstream of Yellow River. According to calculated results, the features of agricultural frangibility were evaluated. Countermeasures on improving agricultural eco-environment of the downstream Yellow River were put forward.
