基于DPSIR模型的流域环境变迁与生态安全指标体系研究

目的]研究基于DPSIR模型的流域环境变迁及生态安全指标体系。方法]在考虑流域环境变迁及生态安全的各类影响因素的基础上,以"驱动力-压力-状态-影响-响应"(DPSIR)模型为框架,提出了在多级开发影响下的流域环境变迁与生态安全指标体系基本框架、原则及相关方法。结果]基于DPSIR模型的流域环境变迁及生态安全指标体系分为驱动力指标、压力指标、状态指标、影响指标和响应指标,每个指标类型又有多个可选指标。结论]该研究为我国流域生态安全评估以及流域生态环境管理实践提供了理论支持和方法借鉴。

Study on Index System of the Environmental Change and Ecological Security for a River Basin Based on DPSIR Model

Objective] The research aimed to study index system of the environmental change and ecological security for a river basin based on DPSIR model.Method] Based on considering each influence factor of the environmental change and ecological security for a river basin,DPSIR model as frame,basic frame,principle and related method of the index system of the environmental change and ecological security for a river basin under influence of the multi-level development were put forward.Result] Index system of the environmental change and ecological security for a river basin based on DPSIR model included driving force index,pressure index,state index,influence index and response index.Each index type also had many sub-indices.Conclusion] The research provided theoretical support and method reference for assessment of the ecological security and practice of the ecological environment management for a river basin in China.
