%X Through analyzing the importance of landscape factors, landscape connectivity, assessment of suitability and fuzzy value of connectivity and establishing a landscape connectivity model that applies landscape ecology and GIS technology, the connectivity level, suitability assessment and fragmentation status of all types of suitability areas were studied. The spatial structure of fragmental landscape of red deer habitats was analyzed from an ecological function perspective because of spatial composition and mismatch in Wandashan region, Heilongjiang Province from Feb.2003 to Mar. 2004. The results indicated that suitable habitats were 14.81 km~2 (only 9.52%), marginally suitable habitats were 9.57 km~2 (6.15%), less suitable habitats were 130.05km~2 (83.58%), unsuitable habitats were 1.17km~2 (0.75%) in the total area of 155.6 km~2. Marginally suitable habitats and suitable habitats included many patches and were isolated fragmentally in the area of study. Although some unsuitable habitats patches (settlements, farmlands, abandoned logging roads, forestry roads and so on.) were relatively small and the extent of their morphological fragmentation was low, they had significant effects on the deprival of ecosystem functions of less suitable red deer habitats directly and of suitable and marginally suitable red deer habitats indirectly.
