Research on Landscape Pattern Evolution of Baihe Forestry Bureau Based on GIS
摘要
Abstract
Based on GIS as well as the theory and method of landscape ecology, the dynamic evolution of landscape pattern of Baihe Forestry Bureau in Changbaishan mountain Region from 1987 to 2000 was analysed with quantitative indexes, and the re-lationship between regional Landscape ecology process and forest landscape pattern evolution was discussed. The result showed that total operation area decreased by 1 663.87 hm2 and patch numbers increased by 4 240 from 1987 to 2000. Due to the influence of physical geography elements and the restriction of socio-economic factors, the regional landscape pattern had formed that forest lands predominated whereas open forest lands, shrub lands, swamp lands and non-forest lands scattered like patches. With the in-crease of human disturbance intensity, the landscape diversity index, the patch density and the degree of fragmentation were in-creased respectively.关键词
