Yunnan Haba Snow Mountain Ecological Safety Evaluation Based on the Landscape Ecological Pattern

Abstract:

Land ecological security research has gradually become concerned field on global. Using on the Haba Snow Mountain as an example try to discuss the evaluation of ecological security based on change of the landscape ecological pattern in the paper. In GIS, RS and GPS support and accordance with the principles of landscape ecology and using new grid map method has been 1993 and 2006 Haba Snow Mountain ecological safety evaluation and space differentiation. There are temperate coniferous forest, grassland, sclerophyll broad-leaved forest, warm coniferous forest, water area, residential land, semi-humid evergreen broad-leaved forest, ice and snow land nine landscape types, and temperate coniferous forest and grassland are dominant landscape in the study area, both area has accounted about 67% of the total area. The results show that from 1993 to 2006 the whole landscape pattern has changed less in the area. Land ecological security level space differentiation is very obvious. Ecological security level high altitude area is superior to low altitude area, the core area is superior to the edge area, north area is superior to the southern area. Land ecological security in the study area whole is in good level. From 1993 to 2006 years land ecological security level has declined in the area. Research on ecological safety planning to provide basis for ecological safety planning and for similar high mountain canyon area also has reference value.
