摘要: 划定生态红线是我国生态环境保护的重要措施之一。对重庆市渝东北生态红线区域生态环境质量进行分析与评价,借助ArcGIS软件,通过构建生态环境质量评估指标体系,耦合集对分析与NPP定量指标法进行评估,弄清影响区域生态环境质量的胁迫因子,探讨区域生态环境未来保护方向。结果表明:北部生态红线区域的生态环境质量为良;南部、中东部生态红线区域的生态环境质量为中;渝东北中部生态红线区域的生态环境质量为差;农作活动强度等10个关键指标对研究区域生态环境质量具有重要影响;未来,梁平生态红线区等8个地区的生态环境质量有向好发展的趋势,万州生态红线区等3个地区生态环境质量有下降的趋势;研究区域生态环境质量与生态系统功能在不同地区呈现出对立和同一关系。该耦合集对分析方法与NPP模型对区域生态环境质量与生态功能服务重要性进行了评价和预测,评价结果符合区域生态环境特征,对典型区域生态环境质量的研究与改善具有一定的参考意义。

Abstract: Delimitation of ecological red line is one of the important measures for ecological environment protection in China. The ecology environment quality of ecological red line area in northeast Chongqing was analyzed and evaluated by using ArcGIS software. Through the construction of eco-environmental quality evaluation index system, the coupling set pair analysis and NPP quantitative index method were used to clarify the stress factors affecting the regional ecological environment quality, and to explore the future protection direction of regional ecological environment. The results show that: the ecological environment quality of the red line area is poor in the center, medium in the south and the center east, favorable in the north of the study area. Ten key indicators, such as the intensity of agricultural activities, have an important impact on the ecological environment quality of the study area. In the future, the ecological environment quality will have a trend of good development in eight areas such as Liangping ecological red line region, and have a declining trend in three areas such as Wanzhou ecological red line region. The ecological environment quality and ecosystem function in different regions of the study area show opposition and identical relationship. The proposed coupling set pair analysis method and NPP model are used to evaluate and predict the importance of regional eco-environmental quality and ecological function services, and the evaluation results accord with the characteristics of regional ecological environment, which can provide reference for the research and improvement of the ecological environment quality in typical areas.

Key words: environmental engineering, set pair analysis, NPP model, ecological environment quality, ecological red line, northeast Chongqing
