| 通州区作为北京市副中心，将有序地承接中心城区人口及功能的疏解，并以资源环境承载力作为通州区发展的硬性约束，严格控制用地和人口规模，以期兼顾城市与生态环境保护的协同发展。对通州区2008—2013年和2013—2018年2个时间段的土地转换进行了分析，同时运用InVEST模型对通州区的生境质量做出评价。研究表明，在2008—2018年间，低度生境质量的增加主要由于林地、草地、水域和耕地等用地类型向建设用地转变，从而导致在2013—2018年间以林地、水域用地类型为主的高度生境质量下降以及2008—2018年间以耕地为主的一般生境质量的比例减少。近年来随着“百万亩造林工程”的实施，通州区按照“两带、一环、一心”的绿色空间结构全面推进了河道绿化和东、西部生态绿带以及东南部森林湿地群的建设，对优化通州区生境质量起到了积极作用。生境质量的评价结果为指导通州区蓝绿交织的城市规划建设和生境保护提供一定的参考依据。 |

| Abstract: |
| As the capital’s sub-center, Tongzhou District will undertake the function of orderly alleviating the population and function burdens of the downtown areas, and strictly control its land use and population size following the rigid constraint of resource environment bearing capacity of the district, so as to achieve coordinated development of the city and the ecological environment. This thesis analyzes the land transformation from 2008 to 2013 and from 2013 to 2018, and evaluates the habitat quality of Tongzhou District with the InVEST model. The result shows that the low habitat quality improved from 2008 to 2018, mainly due to the land use transformation from woods, meadow, water area and arable land to construction land, which led to the decline of the high habitat quality that was mainly based on woods and water areas from 2013 to 2018, and to the decrease in the proportion of general habitat quality which was dominated by arable land from 2008 to 2018. Along with the implementation of the “Million-Mu Afforestation Project” in recent years, Tongzhou District has adopted the “Two Belts, One Ring, and One Core” green spatial structure to comprehensively promote the greening of the paths along the river as well as the construction of the eastern and western ecological green belts and the southeastern forested wetland clusters. These measures have ultimately contributed to the optimization of the habitat quality in Tongzhou District. The research result will provide reference for urban planning and construction of landscape and habitat protection in Tongzhou District. |
