遥感技术在城市规划中的应用——以石河子市为例

Applications of Remote Sensing Technology in Urban Planning and Construction──A Case Study of Shihezi

利用专业遥感图像处理软件,对石河子市不同时期的遥感影像进行几何校正、图像增强和非监督分类等处理,获取城市用地信息,通过对比分析不同时期的城市用地类型,评估城市用地的变化情况。结果表明:(1)研究区内土地利用处于发展期,各种土地利用类型变化大;(2)绿化率较高,但是区域分布差异大,表现为西部老城区绿化率高,而东部开发区绿化率低;(3)耕地面积不断减少,而绿化面积未能及时弥补,所以对市区的环境质量具有一定程度的负面影响。在未来的规划中,应该在保持耕地面积不再减少的情况下,继续增加绿化面积,尤其要增加开发区绿化率,为开发区的后续发展营造良好的环境氛围。

Using the professional software of remote sensing to analysis remote sensing images of Shihezi ,different periods remote sensing images were carried on kinds of procession,such as geometry correction, image enhancement, unsupervised classification and so on. Then the urban land information was gained.Through Comparative Analysising the type of urban land of different periods, the changes of the urban land were evaluated. The results showed：（1） the land use in the study area was in development period and different types of land use has changed a lot.（2） The Green Ratio was high,but the regional distribution was great difference,which mainly manifested as the Green Ratio was high at the western Old City, and low in eastern development zone.（3） The cultivated area was continuously reducing,but the virescence area had been not supplied in time ,which brought as a little negative influences to the environment. In the future planning, the green area should go on creasing in the ease of keeping the cultivated area still not reducing,and especially creasing the Green Ratio in development zone.All the works are just for building a good environment atmosphere for the devolopment zone.
