9 October 2007Landscape ecological risk assessment study in arid land
The ecosystem risk assessment is an essential decision making system for predicting the reconstruction and recovery of a
damaged ecosystem after intensive mankind activities. The sustainability of environment and resources of the lake
ecosystem in arid districts have been paid close attention to by international communities as well as numerous experts
and scholars. The ecological risk assessment offered a scientific foundation for making the decision and execution of
ecological risk management. Bosten Lake, the largest inland freshwater lake in China, is the main water source of the
industrial and agricultural production as well as the local residence in Yanqi basin, Kuara city and Yuri County in the
southern Xinjiang. Bosten Lake also provides a direct water source for emergency transportation in the Lower Reaches
of Tarim River. However, with the intensive utilizations of water and soil resources, the environmental condition in the
Bosten Lake has become more and more serious. In this study, the theory and method of landscape ecological risk
assessment has been practiced using 3S technologies combined with the frontier theory of landscape ecology. Defining
the mainly risk resource including flood, drought, water pollution and rich nutrition of water has been evaluated based on
the ecosystem risk assessment system. The main process includes five stages: regional natural resources analysis, risk
receptor selection, risk sources evaluation, exposure and hazard analysis, and integrated risk assessment. Based on the
risk assessment results, the environmental risk management countermeasure has been determined.
