基于3S技术的黄龙山林地时空动态变化及驱动力分析
Analyses on Spatial-Temporal Characteristics and Driving Factors of Woodland Changes in Huanglong Mountain Based on 3S Technology
摘要
Abstract
ln this paper, we collected the remote sensing data of Huanglong Mountain in the year of 1986, 1997 and 2008, and revealed the temporal and spatial characteristics of forests in this area by using "3S" technology. Driving forces of woodland changes were analyzed, socio-economic driving force models of various kinds of woodlands by using socio-economic statistical resources were bulit. The results showed that existed significant fluctuations of woodland in Huanglong Mountain. The forestedland and other types of woodland were increasing constantly, while the area of shrubland and open forest land were shrinking. There were internal conversions between different kinds of wood lands, and the main trends were that the shrublands and open forest lands transferred to forested land. The conversion rate of forestry resources in Huanglong Mountain was slow down from 1997 to 2008 compared to that from 1986 to 1997. The socio-economic driving force model demonstrated that the forested lands had high relevance to the GDP increase, and other types of forest variation, while the total investment in fixed assets and the proportion of agricultural population were respectively of high relevance with the area changes of shrub forests and open forest lands in Huanglong Mountain.关键词
