地理国情普查数据在林地监测中的应用研究

以黑龙江省穆棱市为研究区,利用2005年的基础地理信息数据和2015年全国地理国情普查数据成果作为基础数据,并结合SPOT-5、ZY-3卫星遥感影像数据,对穆棱市林地进行监测。本文从数据的收集与整理、影像处理和变化监测数据提取及处理方法等进行应用研究,准确快速获取变化信息的光谱、纹理、植被指数及面积等信息,通过特定运算得到每期研究区内植被的覆盖率、保有量以及蓄积量,实现林地覆盖率、保有量及蓄积量的动态变化监测。最后,通过对监测数据的统计分析得出穆棱市林地变化监测成果。

Geographical Conditions Census Data in Forest Land Monitoring Application Research

Muleng city in Heilongjiang province as the research area,using in 2005 basic geographic information data and achieve ments of the national geographic state census data in 2015 as basic data,and combining the SPOTS,ZY-3 satellite remote sensing image data,to monitor the Muleng city forest.Papers from the data collection and sorting,image processing and change monitoring data extraction method and processing methods are applied research and accurate information about the quick change of spectrum,texture,vegetation index and the information such as area,through specific operations for each research area,vegetation coverage,ownership and volume,to implement the dynamic change of forest coverage,ownership and volume monitoring.Finally through the statistical analysis of monitoring data obtained Muleng city forest land change monitoring results.
