苏州市经济发展与环境污染耦合关系的实证研究 总被引:2,自引:0,他引:2
选取苏州市1990-2004年经济与环境数据, 通过分析经济因子与环境因子相互关系,探究苏州市经济增长与环境质量演替轨迹,建立经济增长与环境污染水平计量模型.根据模型结果分析了苏州市环境库兹涅茨曲线的特征及产生的原因,并提出了相应的改进建议.实证研究表明,苏州市部分环境指标与人均GDP演替轨迹呈现一定的环境库兹涅茨曲线特征,但大部分环境指标尚未达到转折点.产生这种现象的主要原因是产业结构的不合理. 相似文献

Despite the popularity of marine protected areas (MPAs) as a management tool, increasing evidence shows that many fail to
achieve conservation objectives. Although several MPAs exist in Sri Lanka, most are not managed, and resource extraction and
habitat degradation continue unabated. At present, the declaration and management of MPAs is carried out without adequate
consideration of the ecology, socioeconomic realities, or long-term management sustainability. Managers have focused more
toward the creation of new legislation and protected areas rather than ensuring the implementation of existing regulations
and management of existing protected areas. Poor coordination and a lack of serious political will have also hindered successful
resource management. As in other developing countries, MPA managers have to contend with coastal communities that are directly
dependant on marine resources for their subsistence. This often makes it unfeasible to exclude resource users, and MPAs have
failed to attract necessary government support because many politicians are partial toward the immediate needs of local communities
for both economic and political reasons. A more integrated approach, and decisions based on the analysis of all relevant criteria
combined with a concerted and genuine effort toward implementing strategies and achieving predetermined targets, is needed
for effective management of MPAs and the sustainable use of marine resources in Sri Lanka. 相似文献
