泾惠渠灌区地下水资源演变与农田生态安全
Groundwater Resources Evolution and Agricultural Ecological Security in Jinghui Canal Irrigation Area
摘要
Abstract
Based on the recharge mechanism and development trends of the groundwater in Jinghui Canal irrigation area,it was pointed out that cli-mate changes,geological condition changes and the negative impacts of human activities had caused the reduction of groundwater resources,espe-cially irrigation diversion and groundwater exploitation. In the meantime,it also pointed out the agricultural ecological security problems caused by groundwater resources reduction,which had threatened the sustainable development of irrigation area. Aimed at these issues,measures to adjust and control water resources were discussed which included irrigation water quantity,distribution of irrigation time and groundwater exploitation. Fi-nally,it pointed out that the combination use of surface water and groundwater were the effective way to realize the sustainability of groundwater re-sources,water supply safety and thus keeping the virtuous cycle of agricultural eco-environment in Jinghui Canal irrigation area.关键词
