- Abstract:
-
The change of land use and ecosystem service value on regional ecological construction and sustainable development is of great significance. This article interpreted remote sensing image of Huanghua City in 1990, 2000 and 1990 by ENVI and ArcGIS, and analyzed the changes of the land types and the values of ecosystem services in the research area. The results showed that during the study period land types presented rules of two types of increasing and five types of decreasing. Garden lands increased in 1 268.95 hm2 and construction lands increased in 4 873.54 hm2. Cultivated land, grassland, water area, saline and unused land reduced. Cultivated land, water area and saline land had important contribution to land ecosystem service values. However, total land ecosystem service value reduced by 72.574 million yuan. Land ecological type changes have the negative impact on the ecological system, and the ecological environmental quality is declining in Huanghua City.
