中国耕地利用集约度结构变化及其区域差异(英文)陈瑜琦 李秀彬 田玉军 谈明洪 【摘要】：Based on the data from the Cost-benefit Data of Farm Produce and the China Agricultural Yearbook, this paper divided the intensity of cultivated land use into labor intensity and capital intensity, and then analyzed their temporal and spatial change at both national and provincial levels between 1980 and 2006. The results showed that: (1) At the national level, labor intensity on food produce decreased from day/ha in 1980 to day/ha in 2006; and a continuous decrease with a steep decline between 1980 and 1986, a slower decline from 1987 to 1996, and another steep decline from 1997 to 2006. On the contrary, capital intensity shows an increasing trend since 1980. As to the internal composition of capital intensity, the proportion of seed, chemical fertilizer and pesticide input decreased from to and the proportion of machinery increased from to . The less emphasis on yield-increasing input and more emphasis on labor-saving input are the main reasons for a slow increase of yield per unit area after 1996. (2) At the provincial level, the developed areas have lower labor intensity and higher capital intensity. The less developed ones have higher labor intensity but lower capital intensity. From the viewpoint of the internal composition of capital intensity, labor-saving input accounts for more proportion in the developed areas than that of other areas. The main reason is that in these developed areas, labor input has become a constraint factor in food production as more and more labors engaged in off-farm work. Farmers increase the labor-saving input for higher labor productivity. However, in the less developed areas, the major constraint is the shortage of capital; food production is still depending on labor and yield-increasing inputs.

Farmland is a scarce resource, in a national economy plays a very important role, is the foundation of the national economy. This article through to each division of zhanjiang cultivated land intensive use situation analyzed, and the cultivated land intensive use to evaluate potential arable land, so as to obtain the best intensive use potential. In the process of analysis and evaluation, this paper USES ahp thoughts, scientific evaluation index system. Use objective method of entropy method and coefficient of variation of hair sure weight of each indicator. Puts forward "reasonable value evaluation index, the reasonable value will be combined with weight, it is concluded that the cultivated land intensive use each partition, and find the best potential arable land intensive use influence factors of best potential play, and at last puts forward some improvement Suggestions.
