基于GIS的黄土高原生态系统服务价值对土地利用变化的响应及生态补偿
Response of ecosystem service values to land use change based on GIS and ecological compensation in Loess Plateau
摘要
Abstract
The Loess Plateau is the most serious soil erosion areas in China, where the land use changes would lead to the various ecological and environmental problems, which has been one of the hot issues around the world. By taking the whole Loess Plateau region as the research object, the land use changes between 1985 and 2005 was studied and the reasons of the changes were analyzed based on GIS technology. The effect of land use changes on the ecosystem service was evaluated quantitatively and an appropriate eco-compensation standard was preliminarily developed. The results show that: 1 ) the main type of land use was grassland and farmland, accounting for over 75% of total land use. Among them, the area of farmland was reducing, and the area of woodland was increasing; 2) Settlement was the most active land use type. Settlement and waterland were expanding between 1985 and 2005 ; 3 ) Land use changes impacted the regional eco-environmental effects. The total value of ecosystem services rose 0. 01% , in which woodland had the biggest increase about 0. 09% and the largest decline occurred in farmland about 0. 02% . The total ecosystem services of the Loess Plateau were increasing, except the values of waste treatment and food production relating with farmland and wilderness; 4) According to the values of ecosystem services of Loess Plateau, the eco-compensation standard was 427. 32 million yuan.关键词
