摘要
以吉林省公主岭市为研究区域,利用气象数据、土地利用数据、数字高程数据、遥感影像数据、农业化肥市场价格统计数据等资料,结合修正通用土壤流失方程(RUSLE)对全域生态系统和农业生态系统的土壤保持价值分别进行了估算.结果表明,2015年全域生态系统土壤保持价值约为125.37亿元(占同年总GDP的28.3％),其中农业生态系统土壤保持价值约为111.07亿元,占全域生态系统土壤保持价值的88.6％;其中包括了耕地保持价值93.48亿元、林地保持价值16.71亿元、草地保持价值0.88亿元.
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.
