基于遥感技术的吉林省生态资产定量评估与动态监测
A Quantitative Evaluation of Ecological Assets and Dynamic Supervision in Jilin Province Based on Remote Sensing Technology
摘要
Abstract
On the basis of the measurement of ecological parameters by using remote sensing technology, combined with the ecological method and TM/ETM + , the authors made a quantitative measurement of ecological assets of Jilin Province in 2000 and 2008, obtained the spatial distribution of ecological assets and carried out a dynamic analysis. The results show that, from 2000 to 2008, the total value of ecological assets of Jilin Province increased from 438.561 billion to 675.131 billion yuan, and the value per unit area increased to 241.7 kilo yuan /( km2 · a).In different ecosystem types, the total value of ecological assets of the forest had the biggest changes, and the increase of the total value amounted to 119.36 billion yuan in 8 years, while the ecological value of the building land had the minimum increase, with the increase of only 1. 575 billion yuan. According to the spatial distribution of the total value of ecological assets, the distribution of total value of Jilin Province's ecological assets in 2000 and 2008 showed the trend of decreasing from east to west.关键词
