Abstract:

Based on the land use data of Zhejiang in 2000, 2010 and 2020, geo-information tupu model regarding cultivated land use transition was constructed, and the spatio-temporal evolution characteristics of cultivated land use transition in Zhejiang Province were revealed by using ArcGIS 10.6 software. It was shown that the cultivated land use transition in Zhejiang mainly consisted of forestland occupation and supplementation, as well as transition to construction land, with a C-shaped spatial agglomeration, and presented remarkable characteristics of east-occupation-west-supplementation, and the spatial distribution changed from Hangjiahu plain, Hangshaoyong region and Yongwen coastal economic belt to the basin hilly region. The amount and separation degree of cultivated land use transition increased, and the occupation area was greater than the supplementation area, yet the gap narrowed. The cultivated land use transition mainly happened in the period of 2010-2020. The forestland was the main source for cultivated land supplementation, and the occupation of cultivated land by construction land was a major concern. In view of this, it was suggested that the stock should be revitalized, the increment should be promoted, and the variables should be tackled. What’s more, the allocation of cultivated land resources should be optimized and the justice of land use should be ensured to finally realize the bidirectional balance of cultivated land supplementation and construction land safeguard, as well as the coordination of trinity system, which consists of ecological protection, food security and development space.
