EFFECTS OF LANDSCAPE CHANGES ON ECOSYSTEM SERVICES: A CASE STUDY IN NANPING, NORTHERN FUJIAN PROVINCE, CHINA

With the support of GIS and RS, the types of land use from 1995 to 2015 in Nanping City, China, were classified and the landscape indices were calculated using FRAGSTATS 4.2 software. Then, the ecosystem service value of Nanping was obtained and finally the correlation between landscape index and ecosystem service function was analyzed via SPSS. The results showed that the landscape patches in Nanping mainly consisted of forestland, grassland, and cultivated land from 1995 to 2015. The area of forestland and construction land increased significantly, while the area of cultivated land dropped sharply. The landscape indices of TA, LPI, and COHESION in Nanping did not change significantly. NP and PD increased at first and then decreased, and the value of CONTAG increased constantly. PAFRAC, ED, and SHDI showed a decreasing trend as a whole, while SHAPE illustrated a volatile situation. In the past 20 years, the value of ecosystem services in Nanping has shown an upward trend. The maximum contribution to total ecosystem service value is from forestland, followed by grassland and cultivated land. The total ecosystem service value was positively correlated with CONTAG and negatively correlated with ED and SHDI.
