Also, the relationship between the directions of arable-land and economic development was investigated according to the statistical data correlated with the statistical yearbook of Yantai.

In this paper,basing on the survey of 1396 households in 74 villages of 38 counties in Jiangxi province,the Logistic regressive model was set up to analyze factors affecting the households behavior in cultivated land transfer out and in.

The management of cultivated land transfer may play an important role in balancing agricultural modernization with household contract responsibility system.

Based on it,we estimated the economic loss of cultivated land decrease from 2000 to 2003.

And there were three height periods of decrease in arable-land: round about 1985,1987 to 1990,and 1991 to 1993 respectively.

This paper estimates the impact on grain production capacity of cultivated land with the most popular C-D production function,the result indicates the cultivated land plays an essential role in improving grain production capacity,and its essence of this kind of influence displays on the cultivated land loss: including reducing of the cultivated area and reduction of cultivated land quality.

The authors analyzed the relationship of cultivated land decrease and GDP per capi- ta in seven sample areas—Shanghai,Zhejiang,Jiangsu,Hainan,Ningxia,Hebei and Henan—by collecting and analyzing the data of cultivated land loss,GDP per capita and industrial structure.
