基于RUSLE的农业生态系统土壤保持价值估算研究
Estimation of Soil Conservation Value in Agro-ecosystem Based on RUSLE
摘要
Abstract
Taking Gongzhuling of Jilin Province as the research area,the soil conservation value of the total ecosystem and agricultural ecosystem in this area was estimated respectively by using meteorological data,land use data,digital elevation data,remote sensing image data,agricultural fertilizer market price statistics,and the modified general soil loss equation(RUSLE).The result shows that the total ecosystem soil conservation value of the entire region in 2015 was about 12.537 billion yuan(accounting for 28.3％of the total GDP of the same year),of which the agricultural ecosystem soil conservation value was about 11.107 billion yuan,accounting for 88.6％of the total ecosystem soil conservation value;This includes a value of 9.348 billion yuan for cultivated land conservation,1.671 billion yuan for forest land conservation,and 88 million yuan for grassland conservation.关键词
