区域资源优势鉴别与农用地利用结构优化

在分析鉴别闽侯县资源优势的基础上 ,采用线性规划法对区域农用地利用结构进行优化 .结果表明 :闽侯县具有耕地、园地和水域等土地资源优势 ,粮食、蔬菜、水果和淡水产品优势 ,劳动力数量、有效灌溉、电气化、化肥投入和保收比重等开发条件优势以及区位和政策优势 .农用地利用结构优化后 ,2 0 10年全县粮食作物、经济作物、蔬菜、青饲料与绿肥、林地、园地和淡水养殖用地将分别比 1998年增长 31.10 %、31.2 0 %、87.5 4 %、37.74 %、3.70 %、14.36%和 2 2 1.31% ,农用地总产值是 1998年的 1.66倍 ,既可充分发挥全县的资源优势 ,又能取得较显著的经济、社会和生态效益

Differentiation of regional resources superiorities and optimization of agricultural land use structure

The use structure of regional agricultural land was optimized by the method of linear programming based on the analysis and differentiation of resources superiorities in Minhou County. The results showed that there were resources superiorities in cultivated land, garden plot and water area, product superiorities of grain, vegetable, fruit and freshwater fish, developing condition superiorities of labour quantities, available irrigation, electrification,fertilizer application and bumper harvesting proportion and superiorities of district and policy in Minhou. After optimization of agricultural land use structure, the areas of grain crop, economic crop, vegetable, forage and green manure, forest land, garden plot and freshwater breeding land in 2010 were increased by 31.10% , 31.20%, 87.54%, 37.74%, 3.70%, 14.36% and 221.31% over 1998 respectively, the total output value of agricultural land in 2010 was 1.66 times of that in 1998, which not only sufficiently developed the resource superiorities, but also obtained higher economical, social and ecological profits.
