摘要:
通过PSR模型建立福建山仔水库生态安全评价的指标体系,应用熵权法确定各指标权重,引入密切值法对水库的生态安全进行评价.结果表明,2000-2003年福州市山仔水库生态安全状况从优到劣的排序依次为:2002年、2001年、2000年、2003年.该研究改进了水库生态安全评价指标体系和传统生态安全评价的数学模型,使指标体系更合理、更切合水库的生态环境保护目标,计算简便,能较客观、全面地反映出评价对象各样本状况.

Abstract:
Using the PSR model, this article has build the evaluation index of the ecological security system, applied the entropy method to define the weight of each assessment index, and applied the intimate data method for evaluating ecological security of Fuzhou Shanzi Reservoir. The results showed that the ecological security situations during 2000 to 2003 from superior to inferior states were in the sequences of 2002, 2001, 2000 and 2003 in Shanzi Reservoir, Fujian Province. The model was simple calculation, objective description and comprehensive reflection of the sample position. The index system was more completely reasonable in needs of the reservoir ecological environmental protection objectives.
Key words:  PSR model  entropy method  intimate data method  ecological security evaluation  Shanzi Reservoir
