济南市历城区农用地集约利用研究

为了对济南市历城区农用地在1995-2008年间的集约利用情况进行研究，通过采用熵值法计算分析历城区统计年鉴资料（2000-2009年）、国民经济统计资料（1995-1998年）和实地调查资料的有关数据，利用GIS、SPSS等相关软件，结合协调系数，研究1995-2008年间历城区农用地集约利用的集约值和协调系数的变化情况。结果表明：研究期内，历城区农用地集约利用集约值较高，发展态势良好；农用地集约利用协调系数较高，生产协调性较好。通过对农用地集约利用中的投入方面、产出方面、土地利用方面、可持续利用方面进行研究得出，在研究期内，耕地总面积及人均耕地面积减少较快，土地供需矛盾突出；农药、化肥等农业生产资料在下降，说明农用地投入的科学合理性明显增强；农用地的产出效益在逐年上升，但北部平原地区高于南部山区；可持续发展状况方面的森林覆盖率和人均耕地在北部平原地区较少；协调系数在研究后期有下降趋势。

Research on the Intensive Use of Agricultural Land in Licheng District of Jinan City

In order to study the intensive use of agricultural land of Licheng District in 1995 to 2008,calculated by using entropy to analysis the national economic statistical data（1995 to 1998）,the statistical yearbook materials（2000 to 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.
