Abstract:

In order to study the intensive use of agricultural land of Licheng District in 1995-2008, calculated by using entropy to analysis the national economic statistical data (1995-1998), the statistical yearbook materials (2000-2009), and field survey data of Licheng District. Using the related software, such as GIS, SPSS and coordination coefficient are to study the intensive use values of agricultural land and coordination coefficient changes of Licheng District from 1995 to 2008. The results of the study indicated that: during the study period, the intensive value of agricultural land intensive use in Licheng District was rising and in good momentum of development; the agricultural land intensive use coordination coefficient was good overall the Licheng District. Through the intensive use of agricultural land in the inputs, outputs, land use, sustainable use of research, the following conclusions: in the study period, the intensive use of agricultural land values in Licheng District were good, but the total area of arable land and per capita arable land area decreased rapidly, the contradiction between supply and demand of land was obvious; pesticides, fertilizers and so on was declining, indicating that investment in agricultural land significantly enhanced the scientific and rational; the output efficiency of agricultural land increased year by year, but in the southern mountainous region was higher than in northern plains; sustainable development aspects of the forest cover and per capita cultivated land in the northern plains is less; coordination coefficient had a downward trend in the late study period.
