摘要:
简述了生态环境状况评价指标构成以及新旧规范中生态环境状况指数影响因子的对比分析。通过对2014—2017年山东省市、县两级生态环境状况的评价与影响因子相关性分析,结果表明,新规范实施后,有林地、灌木林地、湖泊(库)、水田、中度侵蚀、重度侵蚀面积增加对EI评价结果的影响以正面影响为主,其它建设用地、盐碱地面积增加均对EI评价结果产生负面影响,以上8个影响因子对县级EI评价结果的影响明显大于对市级EI评价结果的影响;城镇建设用地面积增加对市级和县级EI评价结果的影响不同,但相比旧规范其负面影响均有所减小;相比旧规范,二氧化硫排放量增加对市级EI评价结果的负面影响明显减弱,但对县级EI评价结果的负面影响明显增大。

Ecological Management Utility Assessment of the Revised Technical Criterion for Ecosystem Status Evaluation in Shandong Province

Abstract:
The composition of the evaluation index of theecosystem status evaluationand comparative analysis of Ecological Index impact factors in new and old codes are briefly described.Correlation analysis of the evaluation of the ecosystem status and impact factors in Shandong Province at the city and county levels from 2014 to 2017 shows that,after the implementation of the new technical criterion, the EI evaluation results were improved with the increasing of forestland area, shrubbery area, lake(reservoir) area, paddy field area, moderate and severe erosion area. At the same time, the increases of other construction land area and saline alkali land area have had a negative impact on the EI evaluation results. The influences of the eight impact factors on the county level EI results were significantly greater than that on the city level EI results. The influences on the evaluation results of city level EI and county level EI were different with the increasing of urban construction land area, but the negative impacts were all reduced in the new technical criterion. Compared with the trialtechnical criterion, the negative impacts of SO2 emissions on the evaluation results of city level EI were significantly reduced, while the negative impacts on the evaluation results of county level EI were significantly increased.
