摘要
生态安全格局是维护城市生态安全的重要保障。以苏州市吴江区为例,在运用生态系统服务价值评估模型核算及分析2004-2016年间生态系统服务价值的基础上,以恢复重要度指数和实际重要度指数为评价指标,优化吴江区生态系统服务价值评估模型,在此基础上,通过采用热点分析、最小累积阻力模型、聚类与异常值等方法,进行吴江区生态安全格局构建虚拟。本研究可为吴江区生态可持续发展决策提供科学依据,同时也能为其他地区的生态安全格局构建提供借鉴。
Ecological security pattern plays an important role in maintaining ecological security and promoting ecological civilization.Based on calculation of ecosystem service value(2004-2016)of Wujiang district of Suzhou by applying ecosystem service value evaluation model,restoration significance index and actual significance index of various services are constructed to optimize Wujiang district ecosystem service value evaluation model.Based on the optimized model and related theories,the ecosystem service value of Wujiang district is visualized and analyzed by applying GIS.In this paper,tools such as hot-spot analysis,minimum resistance model,and clustering and outlier analysis and so on are used to construct the ecological security pattern of Wujiang district.The research can provide scientific basis and practical significance for the construction of ecological civilization and sustainable development in Wujiang district.Also it can provide reference for the construction of ecological security pattern in other regions in the process of rapid urbanization.
