汉江源土地利用预测及发展建议

Land use prediction and development advice in the Hanjiang river source

以3期遥感影像资料为基础,结合高程、坡度、坡向、气温、降水、河网、道路和人口8个因子层,对汉江源未来土地利用状况进行预测。通过预测结果预知未来土地利用格局及生态环境状况,达到警示作用,并可根据预测状况调整近期的土地利用、开发规划相关政策和方案,最终使得现行的土地利用符合未来发展需要。

Based on the three phases of the remote sensing image data,and combined with the elevation,gradient,slope direction,air temperature,precipitation,river network,roads,and population,the future land use of the Hanjiang river source area is predicted. The prediction of the future pattern of land use and ecological environment condition serves as a warning,and helps regulate the polices and practices concerning the recent land use,land tapping and land development planning,and eventually helps to make the current land use meet the future development.
