摘要
由于大量土地被人工利用,城市中景观斑块具有破碎化严重、连接性低等特征,在城市生态网络中不同斑块间的环境协调功能会因为生态斑块的破碎化而受到一定程度影响。因此,评价研究选定区域内生境斑块生态连接度对整个生态网络系统完整性构建具有重要作用和意义。以上海市为例,采用2006—2020年上海市域用地布局规划数据,对现有景观环境按Mapinfo空间中经纬度坐标系栅格化识别分析,从而总结出一种评估区域内景观生态连接性程度的方法。
Because of a large amount of land being used artificially, the landscape patches in the city are characterized by serious fragmentation and low connectivity. In the urban ecological network, the function of different patches will be affected by the fragmentation of ecological patches. Therefore, it is of great importance to evaluate the ecological connectivity of habitat patches in the selected regions. Taking Shanghai city as an example, choosing land use planning data of Shanghai city in 2006-2020 years, we use grid identification to analyze the existing space environment in Mapinfo space longitude and latitude coordinate system. In this way we can conclude regional landscape ecological connectivity degree.
