Abstract

Remote sensing provides a powerful tool for study on Land Use /Cover Change.Two of the most common uses of satellite images in Land Use /Cover Change are land cover mapping via image classification and land cover change via change detection.Taking Kenli County in Shandong Province as a basic unit,using remote sensing image processing software ENVI 3.4and TM data,the whole process of cultivated land information extracting and dynamic change monitoring with TM data is described in this paper.The pretreatment of TM data includes images correction,data registration,data extraction and image enhancement.The image is classified by two methods,screen visual interpretation and supervised classification combined with screen visual interpretation.Both methods could acquire a good result,but the former method needs more manual work.Monitoring results are acquired based on the information extracting results by means of spatial analysis.It concludes that in agricultural regions,the methods of supervised classification combined with screen visual interpretation and post classification comparisons are effective in cultivated land information extracting and dynamic monitoring,especially in the coastal soil salinized regions.
