摘要
为给高速公路沿线地区土地利用规划提供基础数据和科学依据,选取哈大高速公路沿线地区2 000m和5 000m范围作为研究区,以遥感和地理信息系统为主要技术手段,运用ENVI监督分类方法提取研究区土地利用信息,ArcGIS建立土地利用数据库,对土地利用现状进行分析。研究结果表明:高速公路建设对土地利用存在一定的影响,即随着高速公路的建设,土地利用靠近公路的地区受公路影响较强,当远离公路至一定距离时,公路的影响逐渐下降。
To provide basic data and scientific basis for land use planning of the region along highway, it selectes the region along Ha-Da highway ranging from 2,000 m to 5,000 m as the study area, and takes remote sensing and geographic information system as the main technology. The ENVI supervised classification method is used to extract information of land use in the study area, and the AreGIS is used to establish land use database. According to the results, the present situation of land use is analyzed. The research results show that the highway construction has a certain influence on the land use, namely, the influence of land use near the highway is stronger, white being away from the road to a certain distance, the influence gradually decreases.
