Abstract

Land rehabilitation is being carried out throughout the whole country. But in many areas, the main purpose of land rehabilitation is to increase the overall cultivated land area which neglects the eco-construction. Important tasks of modern landscape ecology are to monitor and assess natural resources, to examine the impacts and effects of human intervention and, last but not least, to observe the state of the environment over long periods of time. The objective of this research was to create a method for land rehabilitation project using landscape ecology by combining Geographical Information Systems (GIS) and Landscape Ecology Analysis (LEA). GIS technologies were developed for the digital preparation and analysis of historical maps, and subsequent digital land use mapping. The landscape spatial pattern and influence on landscape were expressed by dominance index, contagion index, cohesion index, etc. Applying those landscape ecology indexes landscape spatial pattern influence caused by the land development and rehabilitation planning of Haizhou coal mine waste area was studied by comparing landscape characteristics between those before and after planning implementation. The analysis of the structural landscape changes proved to be an important aspect.
