城市化过程中土地征用风险表征及对策

从土地征用基本概念和基本特征着手，描述了土地征用的主要风险，其表现为土地征用权力滥用、侵害失地农民的权益、诱发集体土地黑市、诱发社会矛盾等方面。分析了产生风险的“公共利益需要”缺乏明确界定、土地征用的补偿标准偏低或滞后、土地征用及相关制度不健全或存在缺陷等主要原因。提出了控制与规避风险的对策与措施：严格限定公益性用地范围，提高征地补偿标准，扩大补偿范围，完善相关制度，严格土地征用程序。     

良好植被区泥石流防治初探

通过对近年来发生在良好植被区的几次重大泥石流、滑坡灾害的考察,发现植被在泥石流、滑坡形成中的作用有待于进一步认识。通过分析,当中小强度降雨激发下,植被能够削减泥石流、滑坡灾害的规模,甚至抑制泥石流、滑坡灾害的发生;当降雨超过一定阀值后,在水作用下,植被不但不能削减灾害规模,反而增大灾害的规模。在这类地区,简单地使用一般的防治措施,已经不能满足防灾、减灾的需要,客观要求针对这些地区泥石流灾害的形成原因、危害特征,研究防治对策。经初步研究提出3点防治措施:1)加强泥石流滑坡灾害的预测预报工作;2)在重点区域设置自动雨量记录报警装置;3)特别针对漂木拦挡,采取新型结构减轻泥石流的危害。     

20世纪90年代以来中外区域规划研究的对比分析

区域规划是国家政府进行区域管理的重要手段和方式之一。为了落实科学发展观和对区域发展有效宏观调控,区域规划成为国家“十一五”规划的重要内容。本文对比分析了1990年代以来国外区域规划研究的主要进展、以及我国区域规划研究的特点与不足,以期为推动我国当前新一轮区域规划的理论研究和实践创新提供有益启示。

Assessment of sand encroachment in Kuwait using GIS

Assessment of sand encroachment in Kuwait using Geographical Information System (GIS) technology has been formulated as a Multi-Criteria Decision Making problem. The Delphi method and Analytical Hierarchy Process were adopted as evaluating techniques, in which experts’ judgments were analyzed for objectively estimating and weighting control factors. Seven triggering factors, depicted in the form of maps, were identified and ordered according to their priority. These factors are (1) wind energy; (2) surface sediment; (3) vegetation density; (4) land use; (5) drainage density; (6) topographic change and (7) vegetation type. The factor maps were digitized, converted to raster data and overlaid to determine their possible spatial relationships. Applying a susceptibility model, a map of sand encroachment susceptibility in Kuwait was developed. The map showed that the areas of very high and high sand encroachment susceptibility are located within the main corridor of sand pathway that coincides with the northwesterly dominant wind direction.     

Planning for source water protection in Ontario

Ontario began developing a drinking water source protection planning process in 2000, after a rural community's water supply was contaminated by pathogens from agricultural runoff. An expert committee report has recommended legislating a new source protection “sphere of jurisdiction” for municipalities; however, no specific new municipal tools or authorities have been proposed as yet. This paper reports findings from an evaluation of the extent to which existing institutional arrangements for land use planning and water management facilitate or constrain source protection by municipalities. A case study of the Regional Municipality of Waterloo suggests there is the potential to link land use planning more strongly to water management through creative use of existing tools, forgoing the need for major institutional changes.     

Rights or Containment? The politics of Aboriginal cultural heritage in Victoria

Aboriginal cultural heritage protection, and the legislative regimes that underpin it, constitute important mechanisms for Aboriginal people to assert their rights and responsibilities. This is especially so in Victoria, where legislation vests wide-ranging powers and control of cultural heritage with Aboriginal communities. However, the politics of cultural heritage, including its institutionalisation as a scientific body of knowledge within the state, can also result in a powerful limiting of Aboriginal rights and responsibilities. This paper examines the politics of cultural heritage through a case study of a small forest in north-west Victoria. Here, a dispute about logging has pivoted around differing conceptualisations of Aboriginal cultural heritage values and their management. Cultural heritage, in this case, is both a powerful tool for the assertion of Aboriginal rights and interests, but simultaneously a set of boundaries within which the state operates to limit and manage the challenge those assertions pose. The paper will argue that Aboriginal cultural heritage is a politically contested and shifting domain structured around Aboriginal law and politics, Australian statute and the legacy of colonial history.     

江苏省矿山的主要生态环境问题及治理对策

江苏的经济发展较快,对矿产资源的需求量亦大。多年来的无序开采,对生态环境造成很大的破坏和影响,出现了山体植被遭受破坏、土地被占用、环境受污染、诱发地面沉降、地面塌陷等一系列问题,已影响到国民经济的发展。随着省人大和省政府关于限制开山采石和保护环境等政策、法规出台和落实,近几年乱采滥挖现象基本得到了有效的遏制。人们的环保意识得到了加强,不少矿山已逐步开始对环境治理,且初见成效。文章介绍了江苏生态环境现状、存在的主要问题和治理对策,以期引起各级政府和广大民众在对矿产资源开采的同时更要注重环境保护。     

推进煤矸石资源化利用的对策建议

煤矸石是我国排放量和堆存量最大的工业固体废弃物之一，但又是可以利用的资源，只要加以资源化利用，就能会变废为宝。在研究我国煤矸石综合利用现状的基础上，指出了煤矸石综合利用中存在的主要问题，从制定规划、完善经济政策、加强法制建设等方面提出了加快推进煤矸石资源化利用的建议。
