| China’s large-scale irrigation water resources utilization exists generally water resources inadequate, non-point pollution and ecological system is not stable, given its ecological environment problems in China’s agriculture, rural and urban and rural development plays an important role, many scholars both at home and abroad work done extensiveand thorough research for the construction of ecological irrigation.In this paper, based on the former research, the first is the principle of water-saving irrigation and ecological expounds the basic concept; Then established including water-saving irrigation engineering support and irrigation system index, the natural ecosystem index, irrigation and drainage engineering model system index, irrigation water environmental system irrigation management system index index and the five aspects of water-saving irrigation, ecological evaluation index system; And then use the fuzzy comprehensive evaluation model of irrigation level on the ecological evaluation, and combined with engineering example got evaluation results; Finally using Microsoft Visual Studio2008programming platform and database software SQL Server2008developed set more emphases irrigation basic information input query and irrigation ecological evaluation function in the integration of visualization applications-water-saving irrigation computer evaluation system of ecological. This system take the irrigation in jiangsu province as an example, using object-oriented development methods, provide a reasonable basis for the job of the ecological system in water-saving irrigation evaluation through the computer model calculation, system operates simple and fastand result of the evaluation is reasonable,and reached the expected basically so it is practical and practical significance. |
