摘要：运用3S技术,对退耕还林工程新造林信息进行了遥感监测,监测内容主要包括以下5个方面:退耕地的定位及面积量算,退耕还林林种的遥感检查,退耕地块的验收,林木种植密度(株行间距)信息的检查,造林成活率及长势的检查。采用了面向对象的信息提取技术,开发了树冠因子自动提取程序,为退耕还林工程的实施提供技术支持。
Current situation and problems are analyzed concerning the national key ecological project of returning farmland to forest.On the basis of analysis above,methods are proposed on application of ＂3S＂ technology（RS,GIS and GPS） in the project of returning farmland to forest.By using the high resolution remote sensing imagery in the conversion farmland back to forest,the research contents related to five major aspects of the ecological project are as follows： positioning the farmland and measuring its area,categorizing and accepting the farmland,checking planting density,checking survival rate in new afforestation.Tree crown are mapped by using object-oriented image analysis,a program was developed to acquire tree crown factors.An attempt has been made to improve monitoring effect in the project of returning farmland to forest.The results indicated that the methods could be of some valuable in the ecological project.
