Habitat Suitability Analysis of Suaeda heteroptera in Wetlands of Laizhou West Bank Based on GIS

摘要

Along with the development of marine economy, west bank of Laizhou Bay, efficient and economical core area, suffered some degree of damage, and local habitats of Suaeda heteroptera were correspondingly affected. Using geographic information systerms (GIS) technology and HIS model, analysis on habitat suitability of S. heteroptera in tital wetlands of Lanzhou west bank. The results show that: Although high soil salinity in the study area, and serious petroleum and heavy metal pollution, the regional environmental conditions meet the basic survival and growth requirement of S. heteroptera , because its strong salt tolerance, as well as petroleum and heavy metal absorption and accumulation ability, consequently, S. heteroptera can be relatively normally grow in this habitat. Generally, Laizhou Bay is a highly or moderate suitable area for S. heteroptera growth.
