Abstract The total value of ecosystem services in Jilin Province was 1.74×1010 USD·a-1, 3.6% of the total value in China. Wetland contributed the main part, which amounted to 51.3% of the total value. Grassland d:d the smallest part, being 1.6% of the total. Rivers, Lakes, forests, and cultivated lands contributed respectively 29%, 15% and 3.1% to the total. It can be seen that, in JiLin Province, forests, grassland, and cultivated lands, covering more than 90% of the total acreage, accounted to merely 20% of the total ecosystem services value; while rivers, lakes and wetland, 6.2% of the total acreage, accounted to about 80% of the total ecosystem services value. Among the seventeen kinds of ecosystem services, the ecological benefits were 155.21×108 USD·a-1, 88.9% of the total value, far higher than the economic benefits and the social benefits. According to the ecosystem services value of each region in Jilin Province, the sequence was: Baicheng>Yanbian>Songyuan>Changchun>Jilin>Tonghua>Siping>Baishan>Liaoyuan.
