【摘要】：基于绵阳市第二次土地调查数据,运用多样化指数、集中化指数、区位指数及土地利用组合系数,对绵阳市所辖各区县的土地利用数量结构进行定量分析.结果表明,不同区县土地利用数量结构呈现显著差异.主城区土地利用方式多样,山区县土地利用类型集中,丘陵县土地利用多样化程度和集中化程度介于主城区和山区县之间.同时,不同区域的土地利用方式也存在不合理之处,主城区近郊农用地不断被城市建设用地所蚕食,山区县土地利用方式单一、部分耕地被过度垦殖,丘陵县农用地荒置现象日趋突出、土地资源利用效率较低.针对不同区域的问题,提出将传统工业企业由绵阳中心城区向远郊转移、在山区县沿坡地建造梯田并大力发展生态旅游业、在丘陵县及其他农业县对从事耕作业的农户给予适量经济补偿并加快农村居民点迁村并点工作进程等相应改进措施.
[Abstract]:Based on the data of the second land survey in Mianyang City, the quantitative analysis of the quantitative structure of land use in Mianyang was carried out by means of diversification index, centralization index, location index and land use combination coefficient. The results showed that there were significant differences in land use quantity structure in different districts and counties. The land use patterns of the main urban areas are diverse, the land use types of mountain counties are concentrated, and the degree of land use diversification and centralization of hilly counties are between the main urban areas and mountain counties. At the same time, there are some unreasonable ways of land use in different regions. The agricultural land in the suburbs of the main urban area is continuously encroached on by the urban construction land, the land use mode of the mountainous counties is single, and part of the cultivated land is over-cultivated. The shortage of agricultural land in hilly county is becoming more and more prominent, and the efficiency of land use is low. In view of the problems in different regions, it is proposed to transfer the traditional industrial enterprises from the central urban area of Mianyang to the outer suburbs, to build terraced fields along slopes in mountain counties and to vigorously develop eco-tourism. In hilly counties and other agricultural counties, appropriate economic compensation should be given to farmers engaged in farming operations and the process of rural settlements moving to villages and working points should be quickened, and the corresponding improvement measures should be taken.
