开发区建设过程中的生态环境影响研究——以长春高新开发区为例

以长春高新开发区为例，从植被变化、生物物种变化、地表覆盖层变化、能流变化等几方面进行了开发区建设前后生态系统的变化分析。采用景观优势度方法，分别计算了缀块密度、频率、景观比例和景观优势度值。优势度排序绿地最高为23.78%，其次为工业用地20.42%，表明开发区规划合理，在建设过程中高度重视环境保护工作。在建立由社会环境、自然环境和污染环境3个方面共7项指标组成的生态满意度评价指标体系中，明确各指标关系的基础上，对区域生态环境和功能给人们生活、工作带来的满意程度进行了评估。评估结果表明,全区除集中供热率为基本满意外，其他指标均达到完全满意的程度。

Ecological Environmental Impact Analyzing in Construction of Development Area:A Case Study of Changchun High-Technology Industry Development Area

The authors analyze ecosystem change before and after development area construction from vegetation changing,species changing,the earth's surface overlay changing,energy current changing and so on taking an example of Changchun high-technology industry development area.The authors utilize landscape dominance means to calculate decorated blocks density(Rd),frequency(Rf),landscape proportion(Lp) and landscape dominance value(Do).The highest dominance value is green land 23.78%,second is industry land 20.42%,which indicates that the plan of development area is reasonable and the authorities of the development area pay attention to environmental protection.In ecological satisfaction degree evaluating system composed of 7 index in society,nature and pollution environments,based on definitude index contain number relation,contentment degree related to ecology environment and function influencing people's life and work is evaluated in this area.The evaluating conclusion indicates that all the index achieve satisfaction degree completely expect of concentrated supplying heat.The investigation result provides feasible evaluating method for environment impact assessment and environment administer in development area or nearby development area.
