Article Preview

Landscape characteristics and dynamics change are studied based on RS and GIS from 1993 to 2007. The results show that there is a big change in Tangshan Nanhu wetland subsidence in the last 15 years. Construction land, water bodies, woodland regional landscape pattern instead of the landscape of construction land and farmland. The change is caused by mining production and land reclamation activities mainly. Take the forest cover index, grass cover index, wetland index, index of landscape heterogeneity, landscape diversity, biological abundance index and Poor index of ecological as assessment index, use analytic hierarchy process to determine the weight of indexes, evaluate Nanhu area eco-environmental quality. The results show that: From 1993 to 2000, there is a slight decline in environmental quality; and since 2000, environmental quality has become better and better.
