锦屏-苏南±800kV直流输电工程将穿越四川麻咪泽自然保护区实验区。利用保护区植被分布图和输电工程设计资料,对该保护区景观结构受该输电工程的影响进行了分析。结果表明:该保护区景观结构受影响范围主要集中在该输电工程两侧500m范围内,受影响的对象主要是针叶林景观、阔叶林景观、灌丛景观、草甸景观、农地景观和构筑物景观,受影响的景观指数主要是斑块数、斑块密度、边界密度等。
Jinping - Sunan ± 800kV DC transmission project will pass through the experimental zone Ma Limize Nature Reserve in Sichuan. Utilizing the distribution map of protected area vegetation and transmission engineering design data, the impact of the landscape structure of the reserve on the transmission project has been analyzed. The results show that the affected area of landscape structure of the nature reserve mainly lies in the range of 500m on both sides of the transmission project. The main affected objects are coniferous forest landscape, broadleaf forest landscape, shrub landscape, meadow landscape, farmland landscape And the landscape of the structure. The landscape indices affected mainly include the number of patches, the patch density and the boundary density.
