Key Issues in Sustainable Use of Agricultural Water Resources in the Upper Reaches of Minjiang

Agricultural water resource, main body of regional water resources, was affected by multiple factors (e.g. landform, climate, precipitation and water system). Based on the investigation of water resources in the upper reaches of Minjiang, in order to scientifically manage and utilize agricultural water resource in this region, some feasible measures of sustainable exploitation were as follow: 1) expedite ecological restoration; 2) construct new agricultural water conservancy for controlling and managing waters; 3) develop water-saving agricultures for mitigating the pressure of water use after the earthquake; 4) control agricultural non-point source pollution for implementing cleaner agricultural production; 5) specify water rights for strengthening management of water resources. These measures mentioned above optimize disposition of agricultural water resources after the earthquake via source, transportation, irrigation, conservation and use of agricultural waters. Additionally, they could increase efficiency of utilization, reduce negative impacts to environments, and ensure durative of agricultural production .
