构建土地利用规划环境影响评价的指标体系   总被引:25,自引:0,他引:25  
冯春涛 《资源开发与市场》2004,20(6):416-417,420
20世纪90年代中期,土地科学界和生态学界曾提出:"无论将土地作为生产性利用还是非生产性利用,都会形成一种干扰,使生态环境的不确定性增大,从而降低土地利用规划的科学性和合理性".在这一背景条件下,尝试性地按照土地利用类型对其所带来的环境变化影响与效应进行了分析,并在此基础上构建土地利用规划环境影响评价指标体系及可采用的评价方法.  相似文献

A review of criteria for evaluating natural areas   总被引:12,自引:0,他引:12  
Methods for evaluating natural areas have evolved in the last couple of decades to assess the importance of natural areas for the purposes of land-use planning, environmental impact assessment, and planning protected areas. Criteria used for evaluation vary and generally fall into three categories: ecological, or abiotic and biotic; cultural; and planning and management. Abiotic and biotic criteria are reviewed here in terms of three questions for each criterion: What is it—what are the definitions used in the ecological and environmental management literature? Why use it—what are the reasons behind its use? How has it been used—what is the state-of-the-art in assessing the criterion? Cultural criteria are discussed more generally in terms of the commonly used frameworks and the concept of significance. Planning and management criteria are generally related to either the need for management action or feasibility of effective management.  相似文献

To achieve a sustainable development, impacts on biodiversity of urbanisation, new infrastructure projects and other land use changes must be considered on landscape and regional scales. This requires that important decisions are made after a systematic evaluation of environmental impacts. Landscape ecology can provide a conceptual framework for the assessment of consequences of long-term development processes like urbanisation on biodiversity components, and for evaluating and visualising the impacts of alternative planning scenarios. The aim of this paper was to develop methods for integrating biodiversity issues in planning and strategic environmental assessment in an urbanising environment, on landscape and regional levels. In order to test developed methods, a case study was conducted in the region of Stockholm, the capital of Sweden, and the study area embraced the city centre, suburbs and peri-urban areas. Focal species were tested as indicators of habitat quality, quantity and connectivity in the landscape. Predictive modelling of habitat distribution in geographic information systems involved the modelling of focal species occurrences based on empirical data, incorporated in a landscape ecological decision support system. When habitat models were retrieved, they were applied on future planning scenarios in order to predict and assess the impacts on focal species. The scenario involving a diffuse exploitation pattern had the greatest negative impacts on the habitat networks of focal species. The scenarios with concentrated exploitation also had negative impacts, although they were possible to mitigate quite easily. The predictions of the impacts on habitats networks of focal species made it possible to quantify, integrate and visualise the effects of urbanisation scenarios on aspects of biodiversity on a landscape level.  相似文献

城镇建设用地需求预测与配置研究   总被引:11,自引:0,他引:11  
针对我国现行城镇建设用地预测方法存在的问题,对城镇建设用地预测方法进行了探索性研究;通过构建科学的建设用地需求预测方法,为土地利用规划提供科学依据。在C—D生产函数的基础上,提出了土地、资本与产出GDP的要素关系模型、恩格尔系数与人均建设用地面积关系模型和时间序列的ARIMA建设用地模型。对成都市城镇建设用地总量进行了实证分析,对4种预测方法的结果进行了定量评价,并据此提出成都市建设用地的配置方案。  相似文献

Using Multicriteria Methods in Environmental Planning and Management   总被引:9,自引:0,他引:9  
In environmental planning and decision processes several alternatives are analyzed in terms of multiple noncommensurate criteria, and many different stakeholders with conflicting preferences are involved. Based on our experience in real-life applications, we discuss how multicriteria decision aid (MCDA) methods can be used successfully in such processes. MCDA methods support these processes by providing a framework for collecting, storing, and processing all relevant information, thus making the decision process traceable and transparent. It is therefore possible to understand and explain why, under several conflicting preferences, a particular decision was made. The MCDA framework also makes the requirements for new information explicit, thus supporting the allocation of resources for the process.  相似文献
