英文摘要 【Objective】This study aims at exploring the evaluation and conservation of plant diversity, accurately defines the scope of plant diversity protection in Chongqing, and provides robust data supports and accurate positioning services for the formulation and implementation of in situ and ex situ plant diversity conservation strategies. 【Method】MaxEnt, SDMtoolbox and ArcGIS are applied to combine 2 504 plant species in Chongqing with multi-dimensional data such as bioclimate, topography and soil, and accurately map the potential suitable habitat of each plant species through iterative calculation for the assessment and the mapping of plant diversity in Chongqing. 【Result】The habitats of a high plant diversity in Chongqing are 31 550 km² in area, accounting for 37%, which are spatially divided into two plant diversity centers, i.e., one is in northeastern part of Chongqing and the other is in the area of two rivers and four mountains. The plant diversity protection under the background of National Spatial Planning is characterized by the facts that the positioning of Three Gorges Reservoir area in northeast Chongqing is highly compatible with the spatial distribution of habitats with high plant diversity, the ecological protection land is significantly concentrated in the main center of plant diversity in northeast Chongqing, and the ecological protection land has insufficient effectiveness in plant diversity protection. 【Conclusion】 It is proposed to expand the effective range of ecological protection land, construct regional ecological protection land networks, and implement the community ecological protection land strategies integrating the concepts of protection and development, so as to continuously optimize the spatial pattern of ecological protection land and promote the protection of plant diversity in Chongqing.
