Abstract

Abstract: ：cultivated land fragmentation and its average ecosystem service value in Zhejiang province were analyzed. Then the correlation between cultivated land fragmentation and its average cultivated land ecosystem service value was calculated by utilizing bivariate spatial autocorrelation method. The results showed that there was a significant negative spatial correlation between farmland fragmentation and ecosystem service value in Zhejiang province. During the study period, the area with high increase rate of cultivated land fragmentation were distributed in the north Zhejiang plain, the southeast coastal plain and the Jinqu basin, while the low value areas were scattered in the mountainous and hilly areas. And the high value areas of average cultivated land ecosystem service value（AESV） reduction were concentrated in north Zhejiang plain, indicating that the more serious the cultivated land fragmentation, the greater the reduction in cultivated land ecosystem services value.

Key words: cultivated land fragmentation, average cultivated land ecosystem service value, spatial-temporal evolution, bivariate spatial autocorrelation, Zhejiang province
