摘要
传统的复杂地质生态脆弱性评估方法的准确性较低,设计一种新的复杂地质生态环境脆弱性评估方法。获取复杂地质生态环境脆弱性评估数据,根据获取的数据选取复杂地质生态环境脆弱性评估指标,构建生态环境脆弱性评估体系。通过最大—最小范围标准化处理方法,对原始评估指标数据实施标准化处理,并通过OWA算子确定评估体系中各指标的对应权重,进而对计算结果进行一致性检验,通过检验后,该指标权重值即为其生态环境脆弱性的指标评估值,实现了复杂地质生态环境脆弱性评估。测试结果表明,在实验地区生态环境状态良好或较差的情况下,设计方法的评估错误率均较低,实现了准确的复杂地质生态环境脆弱性评估。
The accuracy of the traditional assessment methods of complex geo-ecological vulnerability is low,so a new method of assessment of the vulnerability of complex geo-ecological environment was designed.Obtain complex geo-ecological environment vulnerability assessment data,according to the acquired data,select complex geological and ecological environment vulnerability assessment indicators to construct an ecological environment vulnerability assessment system.Standardize the original evaluation index data through the maximum-minimum range standardized processing method,and the corresponding weight of each indicator in the evaluation system was determined by the OWA operator.The consistency test of the calculation results was carried out.After the test,the index weight value is the index evaluation value of its ecological environment fragility,which realizes the fragility assessment of the complex geological ecological environment.The test results showed that in the case of good or poor ecological environment in the experimental area,the evaluation error rate of the design method is low,and an accurate assessment of the vulnerability of the complex geo-ecological environment has been achieved.
