Abstract:: In this paper, a landscape development intensity (LDI) approach was used to assess the ecosystem health of Huangqihai wetland. Huangqihai Lake and its buffer zones (100～600 m) was taken as the study area, and the land use classifications were extracted from the image interpretation of Landsat MSS, TM, and ETM. Then the landscape development intensity coefficient of different land use types (cropland, grassland, bare land, wetland) were calculated for 1976, 1987, 1993, 1999, 2006, and 2010, as well as the overall weighted LDI index value. The results showed that the LDI coefficients of all types of land use had an upward trend, in which wetland had the largest increasing rate (77%). The spatial distribution of the landscape development intensity coefficient gradually increased from the inner part of the lake to the edge of the lake. The LDI index of the Huangqihai lake and its buffer zones had an upward trend generally, making the ecosystem health aggravating. The study areas were in the state of health from 1976 to 1993, followed by the period of transition from ‘health’ to ‘sub-health’ during 1993—1999, and completely transformed into ‘sub-health’ from 1999 to 2010. The improper farming and grazing, as well as the agricultural non-point source pollution were the main reasons for the increase of LDI index. Therefore, we suggested that the enforcement of regulation should be improved in the protected area, grazing and farming should be banned in the lake, the lakeshore buffer reducing the non-point source pollution should be set up.
