南昌市景观格局演变及其生态网络构建研究

Research on Landscape Pattern Evolution and Ecological Network Construction in Nanchang

城市化进程中对各种自然资源的大力开发导致了大量生态用地被挤占破坏,自然生态系统失衡。因此,在现有的城市现状基底上构建一个系统的生态框架,形成一个完整且稳定的生态空间格局,有利于平衡城市生态环境和城市建设发展、保障城市生态安全、保护城市物种多样性。以南昌市为研究对象,分析其2000年-2020年之间的生态敏感性、土地利用变化转移以及景观格局指数变化,根据分析的数据结果对南昌市的生态网络空间构建提供合理的规划策略,优化南昌市的网络系统。

In the process of urbanization,the exploitation of various natural resources leads to the destruction of a large amount of ecological land and the imbalance of natural ecosystem.Therefore,constructing a systematic ecological framework on the basis of the existing urban status quo and forming a complete and stable ecological spatial pattern is conducive to the balance of urban ecological environment and urban construction and development,ensuring urban ecological security and protecting urban species diversity.Taking Nanchang City as the research object,this paper analyzes its ecological sensitivity,land use change transfer and landscape pattern index change during 2000-2020.The study provided reasonable planning strategies for the construction of ecological network space of Nanchang City according to the data analysis results,so as to optimize the network system of Nanchang City.
