卢氏县集中式饮用水水源保护区划分研究

划分水源地保护区是保障饮用水资源可持续利用的重要措施。在卢氏县集中式饮用水水源保护区的划分工作中,根据《饮用水水源保护区划分技术规范》(HJ/T338-2007),采用现场调研和卫星遥感技术相结合的方法,结合饮用水水源保护区的地形、地标、地物的特点,科学地对卢氏县地下水型、河流型、湖泊型水源地进行保护区划分,并提出卢氏县饮用水水源保护区范围、面积及目标,为卢氏县饮用水源保护规划奠定了理论基础。针对卢氏县饮用水源的特点,提出可行的建议和措施,为下一步饮用水源的保护提供科学依据。     

能力验证的方案设计与实施综述

城市街道峡谷内机动车排放污染物的扩散规律

街道峡谷中机动车排放污染物的扩散取决于屋顶风向和风速,并受街道峡谷宽高比、峡谷两侧街区建筑物高度的对称性和高度分布及街区形状等因素的影响.街道峡谷宽高比接近1时,递升型峡谷以及宽阔街道有利于污染物的扩散;可以通过改变街道线源附近街区内建筑物的高度来明显降低污染物浓度.城市建筑规划中若科学考虑上述影响可以减少街道峡谷内污染物的积聚.

基于行业增长的省级可再生能源规划目标分解

为了有效的把国家可再生能源规划分阶段的落实到各个省市,做好二者之间衔接工作,研究考虑了我国在从发展中国家过渡到中等发达国家时所需要考虑的如何平衡公平与效率之阀关系的问题,结合中国可再生能源发展实际特征,提出一种基于行业增长曲线的可再生能源阶段目标分解模型.模型首先求解出中国不同的可再生能源行业的增长曲线.然后给出可再生能源发展阶段目标函数.结合区域发展规划,给出了各省的阶段目标,为了验证该模型的正确性,以风电、水电和太阳发电为代表能源,结合国家可再生能源整体规划和资源需求分布状况,分阶段提出了各省域的可再生能源发展目标.目标分解参照两个原则(1)可分解原则.国家总量目标可以根据一定的标准在不同地区、部门和行业进行分解,由全社会共同完成发展目标.(2)公平性和区域差异的原则.考虑资源禀赋和社会经济发展水平差距,各地总量目标有所区别.研究对于可再生能源规划的整体实施和监管具有一定的借鉴意义.     

能源规划环境影响评价内容框架实践与探讨

规划环评是环评领域一个新方向。虽然环评法已经实施,但目前在实际执行过程中,对编制的规划如何按照规划环评导则组织规划环评以及对规划环评思路和内容框架尚没有具体的研究。从实践出发并结合环境与发展综合决策的角度,以浙江省2010年电力发展规划及2020年展望的能源类规划环评为案例,对能源类规划环评的内容框架作初步研究。     

关于国家环境保护“十三五”规划的战略思考

在对我国当前环境形势以及未来重大环境保护问题识别的基础上,结合国家生态文明建设新要求,提出了"十三五"环境保护规划体系以及规划目标的设想,并从国民经济绿色化、国土空间功能化、保护环境法治化、环境供给市场化、决策监管科学化、治理主体多元化、环境信息公开化等7个方面给出了基本策略建议,可为制定国家"十三五"环境保护规划提供参考。     

Integrating intraseasonal grassland dynamics in cross-scale distribution modeling to support waterbird recovery plans

Despite much discussion about the utility of remote sensing for effective conservation, the inclusion of these technologies in species recovery plans remains largely anecdotal. We developed a modeling approach for the integration of local, spatially measured ecosystem functional dynamics into a species distribution modeling (SDM) framework in which other ecologically relevant factors are modeled separately at broad scales. To illustrate the approach, we incorporated intraseasonal water-vegetation dynamics into a cross-scale SDM for the Common Snipe (Gallinago gallinago), which is highly dependent on water and vegetation dynamics. The Common Snipe is an Iberian grassland waterbird characteristic of European agricultural meadows and a member of one of the most threatened bird guilds. The intraseasonal dynamics of water content of vegetation were measured using the standard deviation of the normalized difference water index time series computed from bimonthly images of the Sentinel-2 satellite. The recovery plan for the Common Snipe in Galicia (northwestern Iberian Peninsula) provided an opportunity to apply our modeling framework. Model accuracy in predicting the species’ distribution at a regional scale (resulting from integration of downscaled climate projections with regional habitat–topographic suitability models) was very high (area under the curve [AUC] of 0.981 and Boyce's index of 0.971). Local water-vegetation dynamic models, based exclusively on Sentinel-2 imagery, were good predictors (AUC of 0.849 and Boyce's index of 0.976). The predictive power improved (AUC of 0.92 and Boyce's index of 0.98) when local model predictions were restricted to areas identified by the continental and regional models as priorities for conservation. Our models also performed well (AUC of 0.90 and Boyce's index of 0.93) when projected to updated water-vegetation conditions. Our modeling framework enabled incorporation of key ecosystem processes closely related to water and carbon cycles while accounting for other factors ecologically relevant to endangered grassland waterbirds across different scales, allowed identification of priority areas for conservation, and provided an opportunity for cost-effective recovery planning by monitoring management effectiveness from space.     

An assessment of Scottish development planning

The present development plan system in Scotland began in 1975. Its origins and purpose are discussed. Progress in the submission and adoption/approval of local and structure plans and in reviewing these plans is outlined. Performance to date is assessed and means of improvement are suggested, in relation to timeliness, transparency, scope and quality.
