摘要
以哈尔滨市为例,基于Landsat数据,利用遥感技术和GIS技术对2000和2015年的遥感影像数据进行解译分类,通过对分类结果的统计分析,定量研究哈尔滨市15年间的土地利用变化过程,结果显示:哈尔滨市土地综合利用程度较高,区域内耕地面积减少;相反,城市建成区面积大幅增加,区域内绿地面积逐年减少,应注意生态环境维护保持。
The taking Harbin City as an example, based on Landsat data, classification and interpretation of 2000 and 2015 of remote sensing image data using the technology of remote sensing and GIS, through statistical analysis on the classification results, quantita- tive study of Harbin city 15 years of land use change process. The results showed that Harbin city land utilization degree is high, de- crease of cultivated land area in the region, on the contrary the city built area of a substantial increase, regional green space is decrea- sing year by year should be pay attention to the ecological environment maintenance.
