摘要: 基于景观指数分析法、熵权法测算耕地破碎化综合指数,在分析县域耕地破碎化时空演变基础上,通过双变量Moran’s I指数探讨耕地破碎化与其生态系统服务价值的空间关联特征。结果表明,浙江耕地破碎化与其生态系统服务价值之间存在显著空间负相关关系,研究时段内耕地破碎化增幅高值区分布在城镇化迅猛发展的浙北平原、东南沿海平原及金衢盆地一带,低值区分散在山地、丘陵区;地均耕地生态系统服务价值减幅高值区则集中分布在平原、盆地区,可见耕地破碎化越严重,耕地生态系统服务价值受损也越严重。

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
