Abstract

Ecological suitability analysis is one of the key components of wetland park planning. The traditional suitability analysis methods only emphasize vertical process of land landscape unit, ignoring the horizontal ecological process of land landscape unit. In this paper, the largest marshland Xinjizhou at Yangtze Xinjizhou National Wetland Park, China, was chosen as the case study area, while the high-resolution remote sensing image of QuickBird in July, 2008 and 13 spatial point distribution data of bird habitat were collected as the main source of information. Then �??layer-cake model�?� based ecological suitability was analyzed and bird landscape security pattern was constructed, followed by optimization of suitability partition. Studies show that: (1) the bird landscape security pattern in study area is comprised of four sources, three ecological corridors, and two strategic points; (2) after optimization, the crossed places by two ecological corridors has been transformed from low ecological suitability area into appropriate suitable ecological zones; (3) after the optimization, the percent of low ecological suitability area of construction land, cropland and nursery land decreased by 7.34 percent, the percent of appropriate and high suitable area such as herbaceous swamps, forests, increased by 6.37% and 0.37%, respectively.
