区域PRED模型在环境区划中的应用

通过分析区域ＰＲＥＤ模型的特点和结构，显示了该模型在环境区划中的广泛应用前景和重要意义．该模型既丰富了环境区划的理论基础，又使区划的指标体系增加了新的内容，使研究者能更多地着眼于系统的协调发展．

Application of PRED Model in Environmental Regionalization

Some characteristics, like concept, structure and parameters, of PRED moded (population, resources, environment and development problems) were analyzed. It shows that PRED model could be applied widely in environmental regionalization and planning, which can make some development and progress in the field of environmental regionalization. Basing on this model researchers will pay more attention on the balance and coordination of environmental system and eco social system.
