广东韶关丹霞山生态系统多样性及其空间定位
Ecosystem biodiversity and spatial location of Mountain Danxiashan in Shaoguan,Guangdong
摘要
Abstract
The sophisticated topography and geomorphology of the Danxia landscape shaped high ecosystem diversity,but it has not been systematically classified,and its spatial location and the characteristics of the main ecosystem types have also not been well investigated.This study focuses on the Danxiashan National Park in Shaoguan and proposes an ecosystem classification system for Danxia geomorphic types under the IUCN global ecosystem classification framework,together with the vegetation types and special topographic and geomorphic characteristics of Mt.Danxiashan.Through remote sensing data and field survey work,the ecosystems were spatially positioned and visualized mapping was implemented.The results show that there are 81 different ecosystem types within the reserve,including 3 types of level I,6 types of level Ⅱ,12 types of level Ⅲ,28 types of level Ⅳ,and 81 types level V.In addition,the spatial positioning and pattern analysis of various levels of ecosystems were conducted,with special attention given to the 4 characteristic ecosystems of Mt.Danxiashan,including 23 categories of mountaintop ecosystems,13 categories of valley ecosystems,4 categories of cave ecosystems,and 4 categories of cliff ecosystems,each of which was displayed separately and spatially.This study has revealed the unique topographic and geomorphic characteristics and ecosystem diversity features of the Mt.Danxiashan area,deepened the understanding of the ecosystem diversity and formation mechanism of Mt.Danxiashan.The data can serve as an important reference for the protection and management of ecosystems in protected areas.关键词
