Evaluation on Ecosystem Services Value Based on Food Production in Nanfen District of Benxi City, Northeast China

摘要

Ecosystem service values based on food production were estimated in Nanfen District of Benxi City, Liaoning Province, Northeast China. Two remote sensing images (1995, 2006) were applied to obtain land use change information and the most recently published value equivalent were used to valuate ecosystem services. The total value of ecosystem services in Nanfen District was 1294.1 million Yuan in 1995 and 1293.49 million Yuan in 2006, with a decrease of 568.3 thousand Yuan mainly due to the declining areas of cropland, water body and wetland. We concluded that future local land use plan should give priority to the conservation of these ecosystems, in order to promote and maintain the balance of local ecosystem.
