摘要
采用可拓学评价方法构建了灌区生态安全综合评价模型,用PSR模式建立评价指标体系,并用综合集成赋权法确定指标权重,对陇川灌区的生态安全进行了评价。结果表明,陇川灌区的生态安全综合评价结果为极不安全。从工程措施、生物措施、农业耕作技术、提高经济发展水平等几方面提出针对性措施。
The assessment model based on extension theory was constructed to assess irrigating area ecological security in Longchuan.Furthermore,PSR model was used to build the index system of ecological security evaluation and the method of comprehensive integration endue-weight was used to ascertain index weight.The result indicated that the irrigating area ecological security was the highest insecurity.In the end,a series of measures including engineering,biology,farming and economy technology were taken to improve the ecological security.
