基于目标物种迁移路径识别的生态廊道构建研究——以成都市东部区域为例

Research on the Construction of Ecological Corridor Based on the Identification of the Migration Path of Target Species——Taking the Eastern Area of Chengdu as an Example

在城市中构建生态廊道连接生物栖息地对生物多样性保护、促进城市可持续发展、实现生态文明建设有重要作用。以成都市东部区域为例,探索了适用于城市及周边区域生态廊道的构建方法,通过确定目标物种、开展生境适宜性评估、模拟生物迁移路径,并综合不同物种的空间需求和既有规划预留的空间条件,构建形成了四级生态廊道体系。其中,一级廊道为龙泉山城市森林公园,二级廊道宽度不小于600m,三级廊道宽度不小于200m,四级廊道宽度不小于60m。研究方法和结果对其他城市的生态廊道规划和生物多样性保护具有一定借鉴意义,对实现人与自然共生共荣、生态文明建设有一定价值。

Connecting biological habitats through the construction of ecological corridors plays an important role in biodiversity protection,and it is also an important part of promoting the sustainable development of cities and realizing the construction of ecological civilization.Taking the eastern region of Chengdu as an example,this paper explored the construction method of ecological corridors suitable for the city and its surrounding areas,and constructed a four-level ecological corridor system by identifying target species,carrying out habitat suitability assessment,simulating biological migration paths,and integrating the spatial requirements of different species and the space conditions reserved in the existing planning.Among them,the first level corridor is Longquan Mountain Urban Forest Park,the width of the second level corridor is not less than 600 m,the width of the third level corridor is not less than 200 m,and the width of the fourth level corridor is not less than 60 m.The research methods and results have certain reference significance for the ecological corridor planning and biodiversity protection of other cities,and have certain value for realization of the coexistence and co-prosperity between human and nature,and the construction of ecological civilization.
