基于ESV和电路理论的粤港澳大湾区生态网络搭建
Ecological network construction based on ESV and circuit theory in the Guangdong-Hong Kong-Macao Greater Bay Area
摘要
Abstract
The ecological network construction can effectively connect habitat patches,protect biological habitats and alleviate ecological and environmental problems.This study takes the Guangdong-Hong Kong-Macao Greater Bay Area as the study area and constructs an ecological network based on the basic pattern of"identification of the ecological source,construction of comprehensive resistance surface,and generation of ecological network".Based on the ecosystem services value(ESV),it calculates the ecological source sites.It uses the circuit theory to extract the corridor,pinch point and barrier point,and the width of the corridor is visualized by the current width.The results showed that:(1)The total ecological source area in the study area was 18042 km2,and the ecological source area was mainly distributed in the Pearl River and mountains.(2)There were 130 conservation ecological corridors and 34 restoration ecological corridors,totaling 4075 km.The corridors were in the shape of weaving nets,and some intersected at the Pearl River's mouth.(3)There were 86 km2 of ecological pinch area in the study area,which were mainly located in the central urban agglomeration of the study area.There were also 179 km2 of restoration barriers,mainly in the Pearl River Delta and its eastern urban agglomeration.(4)For ecological protection in the study area,it was suggested to protect and restore ecological corridors and key points,and improve forest and grass coverage to enhance the overall ecological connectivity.It also proposed to strengthen the protection of the Pearl River Basin and maintain the biodiversity of the coastal zone.(5)For the urban construction in the future,it was suggested to avoid the negative effect of new construction to the conservation corridors,and buffer zones should be set aside in the planning.The area of tree lawns and sheltering forests should be strengthened,and small patches could be added to ensure the circulation of species.关键词
