摘要
以文山州为例,结合InVEST模型、MSPA选取生态源地,利用MCR模型和电路理论提取生态廊道和生态节点,构建文山州区域生态网络,明确在开发建设过程中应优先保护和修复的地区。结果表明,识别生态源地共143个,总面积为5 092.74 km2,主要分布在文山州东部,地类现状以林地为主,植被覆盖度高生态基底好;提取生态廊道346条,空间分布明显,尤其是西部区域连接文山州北部与中部的廊道,其分布稀疏且长度较长,易发生断裂;识别生态夹点118处、生态障碍点41处,应对生态夹点和生态障碍点开展重点保护和修复。
Taking Wenshan Prefecture as an example,this research combined InVEST model and MSPA to select ecological sources,used MCR model and circuit theory to extract ecological corridors and ecological nodes to construct Wenshan regional ecological network,and to identify the areas that should be protected and restored in priority during development and construction.The results showed that 143 ecological sources with a total area of 5092.74 km 2 were identified,which were primarily distributed in the eastern part of Wen-shan Prefecture.The current land type was mainly woodland with high vegetation coverage and good ecological foundation.346 ecological corridors were extracted,and their spatial distribution was obvious.The corridors in the west connecting the north and middle of Wenshan Prefecture were sparse,long and easy to break.There were 118 ecological bottleneck points and 41 ecological barrier points that need protection and repaired.
