基于产业结构变化的区域生态环境效应分析与评价——以湖南省常德市为例

Analysis and Evaluation on the Eco-environmental Effect Based on the Change of Industrial Structure——A Case Study of Changde City of Hunan Province

定量分析产业结构变化对生态环境的影响,反映人类经济活动与生态环境的关系。利用不同产业的生态环境影响指数和资料分析法,分析和评价了湖南省常德市"十一五"期间产业结构变化及其生态环境效应。结果表明:(1)产业结构变化对生态环境质量有显著的影响,第一、二产业内部结构层次低,第三产业比重低,容易造成生态环境破坏;(2)产业结构变化的RCIIISNE值呈现出持续上升趋势,与GDP呈正相关性,对生态环境的干扰与影响程度处于中等水平;各县(区、市)RCIIISNE值呈波动性变化,幅度不大,保持在2.5～3.5,但空间差异明显;(3)三次产业结构对RCIIISNE值的影响差异明显,第二产业远大于第一、三产业,第一产业中农业>牧业>渔业>林业的结构形势,不利于RCIIISNE值的降低;第二产业中重工业和轻工业对RCIIISNE值的负态影响最强。

In order to quantitative analyze the effects on the ecological environment from the change of industrial structure,and reflect the relationship between the economic activity and the ecological environment.From 2006 to 2010,the ecological influence effect of industrial structure in Changde City of Hunan Province was analyzed and evaluated by using R CIIISNE and material analysis.The results were as follows：（1） the industrial structure had significant effects on the quality of the ecological environment,the low and imperfect industrial structure easily destroyed the ecological environment.（2） The R CIIISNE of industrial structure appeared up-trend constantly,and direct correlation with GDP,the ecological influence interference of industrial structure was in moderate.The R CIIISNE of different region appeared fluctuation,but their ranges were not obvious,and keep between 2.5 and 3.5,but the special differences of different region were obvious.（3） The industrial structure had a different impact on the R CIIISNE,the second industry was badly.The structural features had a adverse impact on the R CIIISNE,which was successively composed of agriculture,animal husbandry,fishery and forestry in the first industry.The greatest adverse impacts on the R CIIISNE were heavy industry and light industry.
