Spatial-temporal Variance and Its Impact Factors of Cultivated Land Intensive Use in Zhejiang Province
According to the statistical and survey data of land use change in Zhejiang Province from 2002 to 2011 and the date of the cities in Zhejiang Province in 2012
aiming at the cultivated land intensive use
the evaluation index system of cultivated land intensive use was established
which included 4 aspects and 12 specific indicators from the aspects of input intensity
output level
utilization degree and sustainable conditions of land. We evaluated the time serial change law of cultivated land use in Zhejiang Province and appraised the spatial variation characteristics of cultivated land use of the cities of Zhejiang Province through the efficacy coefficient method. The results showed that:the temporal variability of intensive use level of cultivated land was very obvious and the level of cultivated land increased with volatility in recent 10 a. The spatial variance of the intensive use was remarkable
showing a trend of higher in north area and lower in south area. The socio-economic development
agricultural development and policy factors were the three main factors that affected the situation of cultivated land intensive use.
