Analysis on the variation of cultivated land and direct influencing factors during 1996 to 2006 in Zhejiang Province - based on land survey results.

[Objective] The paper aimed at exploring the variation of cultivated land and influencing factors during 1996 to 2006 in Zhejiang Province more directly,comprehensively and accurately.[Method] The variation of the amount of cultivated land in Zhejiang Province and direct influencing factors had been analyzed using the land survey results of last 10 years.[Result] The cultivated land area of the whole province was reduced by 208 thousand hm2 with a decrease amplitude of 9.8%;terrain slope had played a direct role among the natural influencing factors of cultivated land variation,the cultivated land areas of flats and abrupt slopes were reduced more rapidly,while the terrace areas of gentle slopes had increased;among the social driving forces,the agricultural structure adjustment,construction land expansion and implementation of ecological restoration policy had directly led to the decline of cultivated land areas,while the strict cultivated land protection policy had slowed down the loss of cultivated land.[Conclusion] In conclusion,the declining trend of cultivated land areas is inevitable,so that more scientific general planning of land utilization and more strict land policy has to be utilized more fully in order to guarantee the social and economic development and protect the cultivated land.
