在旅游业高速背景下,探究所辖子区域旅游经济演化情况及联系强度,对指导区域旅游发展布局有实践意义。研究基于修正的引力模型并结合社会网络分析法,分析了贵州省旅游经济网络结构的时空演变特征及驱动因素。结果发现:(1)贵州省旅游经济联系结构日趋合理,打破了贵阳市“一枝独秀”的单一增长极,出现遵义市、黔东南州、安顺市新的增长极。(2)核心城市持续增多,区域旅游发展由单极化向多级化演变,核心城市逐渐从贵阳市逐渐扩展至遵义市、黔东南州、安顺市、毕节市、黔南州。(3)整体旅游经济网络逐渐由松散关系向紧密关系迈进。核心城市呈现出“三足鼎立、五强矗立、七区联合”的演进趋势。边缘城市六盘水市、黔西南州需加大政策扶持,加强旅游基础设施建设,加大涉旅项目投入,逐渐消解其边缘性。 相似文献

环境影响评价是环境管理的重要组成部分,为我国的环境管理决策提供重要依据。但在实际工作中,我国的环境管理工作仍然存在一定的问题。本文结合采掘行业的特点,分别从法律层面、设计层面和环境影响评价层面等三个方向进行分析,结合发现的问题提出建议,力求从不同的角度完善相关制度和技术要求。从而使采掘行业的环境管理能全面涵盖采掘行业开发过程,最大程度地减少采掘行业开发过程中的环境影响,完善采掘行业环境影响评价制度,对我国采掘行业生态环境的改善及环境影响评价法制建设起到一定的借鉴意义。 相似文献

Integration of Environmental Assessment into the Regional Development Planning Process of the Galilee 总被引:2,自引:0,他引:2
/ The Galilee region on the northern edge of Israel constitutes more than 15% of the state's territory, supplies more than half of its drinking water needs, and is an important recreational resource and destination for Israelis. One of the main objectives of the plan for the Galilee was to devise a regional physical and economic development strategy for the years 1992-2007 that would arrest the trend of emigration of its residents, attract newly arrived immigrants to the region, and at the same time protect natural resources and environmental quality. This paper is limited to discussion of the environmental aspects of the plan. It analyzes spatial concepts for distribution of projected population growth, evaluates environmental impacts of alternative plans, and proposes a decision-making framework and tools for minimizing natural resources loss from development at the local level. Assessment of potential environmental impacts generated quantitative data of natural resources areas. Application of the data in the plan evaluation stage showed that the alternative that concentrated most of the new development in central Galilee was the second-best choice environmentally, but was preferred as the best choice for overall qualities. The planning study offers an alternative environmental impact assessment (EIA) process to the one presently used in Israel by incorporating environmental considerations at the initial plan-making stage and not at the plan-approval stage. It demonstrated that in order to be effective, environmental assessment and land-use planning should be seen as one effort that is integrated from the start and in each stage of the plan-making process.KEY WORDS: Environmental assessment; Development planning; Galilee 相似文献
