衡阳市城市土地集约利用研究 总被引:1,自引:0,他引:1
随着衡阳市工业化、城市化和现代化的迅速发展,土地问题已成为制约衡阳市经济发展的关键因素.对城市土地集约利用进行了研究,不断提高城市土地利用效率,有利于城市土地资源的优化配置和合理利用.在介绍衡阳市土地概况的基础上,采用层次分析法,从影响城市土地利用的因素出发,选择土地投入水平、土地利用程度、土地经济产出、社会生态效益四个准则层建立了适合衡阳市城市土地集约利用的评价指标体系.对衡阳市2000-2006年的土地集约利用分值进行了计算,结果表明衡阳市处于基本集约利用的状态,集约利用水平呈曲线上升趋势,并在分析评价结果的基础上提出了实现衡阳市城市土地集约利用的建议. 相似文献

济南市农村居民点用地分析及节约利用对策 总被引:3,自引:1,他引:3
随着城市化水平的提高以及城市规模的扩大,耕地日趋减少,城市用地需求量不断增加,用地矛盾加剧。通过对济南市农村居民点用地现状分析,指出了农村居民点用地存在的问题,土地利用程度低、土地资源浪费是农村居民点用地普遍存在的现象。在当前建设节约型社会的形势下,从提高土地利用程度等方面提出了节约用地的措施,指出平原地区是今后土地利用的重点;采取合理的经济措施,是解决农村居民点用地流转的新途径。 相似文献

河南省是我国农业大省,也是人口大省,人地矛盾较为突出,各地市农村集体建设用地自发进入土地市场隐形流转已相当普遍。实践发展迫切要求规范农村集体建设用地流转,创新集体土地使用制度,建立合理的农村集体建设用地流转配套制度。因此,研究河南省农村集体建设用地流转的现状、规律及其存在的问题,制定合理高效、符合河南省实际的集体建设用地流转措施,规范农村集体建设用地流转市场已成为当前最迫切的问题。选择以河南省农村集体建设用地流转为研究对象,通过理论研究与实证研究相结合,分析了河南省农村集体建设用地流转的现状,探讨了其存在的主要问题及制约因素,提出了规范河南省农村集体建设用地流转的对策和建议。 相似文献

Until the late 1960s rural Hong Kong had an attractive rustic landscape and a small but active farming population. The recent widespread agricultural decline provided opportunities for urban-oriented activities to invade, mainly as open storage and workshops unsuitable in city areas. Rapid container-port expansion and cross-border China trade generate demands for cheap and accessible land for non-conforming uses (NCU). Rural development control and land-use planning are inherently weak, and formal provision for such uses is lacking. An unfavorable landmark court judgement allows landowners to degrade the countryside. The activities have caused acute environmental problems, telescoped into a small territory, including visual blight, pollution, drainage blockage, loss of wetland habitats, and increased flooding hazard. The distinction between urban and rural has been blurred in the destruction of the valuable countryside heritage. An interim legislative amendment fails to stop unauthorized conversion of farmland. In the long term, an integrated and comprehensive rural planning strategy to conserve inherent elements, as well as accommodating selected urban spillover in properly located and serviced sites, is needed. 相似文献

Assessing Land-Use Impacts on Natural Resources 总被引:3,自引:1,他引:2

/ Much information is available on changes that occur in natural resources from both spatially-explicit data on environmental conditions and models of the interactions of these conditions and resources with human activities. The strategy for assessing land-use impacts on natural resources developed in this paper provides a framework for using relevant data and models to address questions of how management practices can promote both use and protection of resources. This assessment strategy integrates spatially explicit environmental data using geographic information systems (GIS) with computer models that simulate changes in land cover in response to land-use impacts. The computer models also simulate susceptibility of species to changes in habitat suitability and landscape patterns. The approach is applied to management of limestone barrens on the Oak Ridge Reservation in East Tennessee. Potential limestone barrens habitats are identified by overlaying appropriate soils, geology, slope, and land-use/land-cover conditions. Their validity is tested against known sites containing rare species that occur in these habitats. The location of habitats at risk in the aftermath of human activities is determined by using an available area model that identifies the size and proximity of sites that particular types of species can no longer use as habitat. The resulting risk map can be used in land management planning. The approach uses readily available in situ and remotely sensed data and is applicable to a wide range of locations and land-use scenarios. This approach can be refined based on needs identified by land managers and on the sensitivity of the results to the resolution of available resource information.KEY WORDS: Land management; Assessment; Habitat characterization; Limestone barrens; Ecological modeling; Geographic information systems 相似文献
