区域可持续发展的环境约束机制

THE BINDING MECHANISM OF ENVIRONMENT ONREGIONAL SUSTAINABLE DEVELOPMENT

区域可持续发展受多种因素制约。环境是区域可持续发展的重要约束因素之一。环境对区域可持续发展的约束主要通过空间条件、资源状况、环境容量及可塑性等因素进行。这些因素的共同作用构成了环境约束机制。环境约束机制最初是由区域持续发展过程中人类行为启动的。它通过被动的适应演变为主动的影响，最后制约区域持续发展。由于环境条件自身能依据客观规律发展变化而具有一定的可塑性，在实施区域持续发展战略中遵循环境规律既能达到预定目的，又能改变环境条件，并可为进一步发展创造新的有利的基础。环境演变与区域可持续发展之间有着约束与反约束关系。这种约束与反约束是通过人类活动启动的，并通过二者的共轭演进实现，其最终结果是二者达到动态平衡。

egional sustainable development is restricted by many kinds of factorsEnvironment is one of the important factorsEnvironment binds regional sustainable development mainly through the space condition,the resource situation,environment capacity and plasticity,and so onThese factors common function constitutes the binding mechanism of environmentThe binding mechanism of environment is firstly operated by human behaviour during regional sustainable developmentIt becomes active influence through passive adaption,then it restricts regional sustainablc developmentBecause environment has a certain plasticity in terms of changes of objective rules,if we follow the environment rules during carring out the strategy of regional sustainable development,we can not only reach the aim,which has been planned already,but also change the condition of environment and create a new advantageous basis for the further developmentThere is a kind of relationship of binding and anti-binding between the environment evolution and regional sustainable developmentSuch binding and anti-binding is operated by human activity,and it is realized through conjugate evolution each otherAs a result,both reach the dynamic equilibrium
