土地荒漠化问题是一个全球性的问题,联合国环境与发展大会于1994年6月通过了世界第一个《防治荒漠化公约》。我国的相关法律规范也涉及到防治荒漠化的内容和措施,但由于相关法律还不完善,荒漠化问题仍十分严重,文章针对这一问题,探讨了如何防治荒漠化的策略和手段。  相似文献

新疆土地退化的成因分析与防治对策--着重于土地的荒漠化   总被引:10,自引:1,他引:10  
舒强 《新疆环境保护》2000,22(3):149-154
新疆地处亚欧大陆腹地,远离海洋,四周环山,幅员辽阔,土地面积居全国各省(区)之首,约占全国土地面积的1/6,但是人类赖以生存的绿洲面积仅占总面积的2.39%,人均耕地面积0.19hm^2,虽然高于全国人均水平,但耕地质量差,复种指数低,产出率低,同时还受到荒漠化的影响。文章通过对新疆荒漠化土地的分布与现状,以及其对农、牧、林、交通运输线路、居民建筑等的危害的综述,探讨了新疆土地荒漠化的主要原因,并为进一步更好的利用、保护土地提出了几点建议。  相似文献

荒漠化通常被认为是自然和人为原因造成的土地荒芜、贫瘠、环境恶化,治理荒漠也因此成为环境保护的重要议题。但事实上,在荒漠化的问题上存在很多认识误区,流行的治理方法也不尽人意。特别是对于那些无需治理、具备重要生态价值的荒漠进行人为治理,不仅不能保护环境,反而破坏了生态平衡。  相似文献

随着我国沿海经济发展战略的实施,经济特区、沿海开放城市和开放地区的“三资”(外商独资、中外合资、中外合作经营)企业迅速发展,有力地促进了我国经济持续稳定的发展,如厦门经济特区1988年“三资”企业工业产值超过了国营企业工业产值。“三资”企业的发展对我国环境保护事业又有什么影响?“三资”企业的发展究竟有无环境问题?我们应该采取怎样的环境保护对策?这是值得研究的问题。  相似文献

为充分发挥龙湖湿地的资源优势和旅游潜力,实现区域经济和生态环境保护的双赢,通过实地抽样调查、数据归类分析等方法,初步探讨了龙湖湿地的资源优势和面临的规划设计不科学、开发利用方式单一、生态入侵形势严峻等环境问题。建议从调控城市湿地生态系统与周边陆域生态系统的耦合关系入手,运用强化湿地管理、加大科技投入、提高群众保护意识等手段,构建一个和谐的生态环境。  相似文献

Sustainability is a concept that has been widely embraced both politically and intellectually but has not been addressed in terms of practical application. In most resource sectors, the features of a sustainable future remain unclear and there are few examples that give practical expression to sustainability. This is especially true in the case of water resources management which has been conspicuous in its absence from the majority of the literature. This paper attempts to address this deficiency on two counts. First, it provides a discussion of sustainability and the application of the concept to the management of water resources. Second, the paper illustrates how the concept can be utilized for the management and planning of urban stormwater. The paper concludes by offering research opportunities to investigate the feasibility of adopting natural channel design and artificial wetlands for sustainable stormwater management.  相似文献

One consequence of the transition of rural communities from industrialised agriculture and natural resource extraction to sustainable development principles has been the rise of community-based natural resource management (CBNRM). CBNRM entails collaborative efforts, typically involving local, state and federal agencies, private firms and landowners, non-governmental organisations such as environmental and economic development groups, and watershed councils. There are no agreed-upon metrics or even broadly accepted approaches for assessing the effectiveness of these new institutions. A good deal of work has been done on evaluating collaborative processes and some on environmental outcomes, but almost none on the socio-economic effects of their activities. To help fill the gap we have been conducting a long-term action research project in Oregon, an analysis of the most effective approaches to the design and implementation of measures of the socio-economic health of communities in which watershed stewardship organisations are active. In this paper we present one case, a participatory process developing socio-economic measures for monitoring CBNRM. We describe the process and the resulting measures. It is expected that the measures will be systematically updated and tracked by the community over the next decade or more. The case study illustrates the necessity and challenges of developing measures for CBNRM that are locally meaningful.  相似文献

自然资源资产负债表的编制是生态文明建设制度创新的一项重大举措。本文依据\"先实物后价值、先存量后流量、先有形后无形\"的原则构建自然资源资产负债表框架结构,在遥感和GIS技术支持下探索自然资源资产负债表编制核算路径,确定土地资源、矿产资源、水资源、林木资源、土壤资源、大气资源等六类有形资产核算指标,以及生物多样性维持功能、碳固定功能、水源涵养功能、土壤保持功能等四类无形资产核算指标,并以浙江省为例,完成了浙江省自然资源资产负债表的编制与其核算过程。研究结果表明:①浙江省2014年自然资源资产存量价值约为126 800亿元,相当于当年浙江省GDP的3倍,是浙江省可持续发展的重要基础;② 2000-2014年浙江省自然资源资产存量价值总体呈上升趋势,固定资产存量价值增加900亿元,无形资产存量价值增加200亿元;③ 2000-2014年浙江省自然资源资产负债累计2100亿元,大气资源负债占比最高,达39.07%,其次是水资源负债,达27.07%。本文提出的自然资源资产负债表编制与核算经验,可为全国自然资源资产负债表编制提供有益探索。  相似文献

A conceptual model is developed herein for the purpose of stimulating discussions within groups planning and carrying out integrated natural resource projects. We first describe four basic components of integrated planning and modeling efforts: people, databases, technology, and organizational commitment. Second, we provide one view of the relationship between the size of the project's decision-making body and the timing of decisions during a project's life cycle. Finally, these two discussions are combined into a conceptual model describing the dynamic nature of decision-making within integrated projects. The abstractions and generalizations described here are not unique to private industry or governmental organizations and should provide the basis for a discussion of decision-making issues among interdisciplinary professionals embarking on large-scale or complex modeling efforts.  相似文献

Bangladesh is one of the most densely populated countries in the world with a very low per capita income. The increasing poverty and instability in the political front led to degradation of the environment and natural resources in the country. The present article reviews the current use of natural resources in Bangladesh and the emerging issues in sustainable management of those scarce resources. The paper shows that developments in one sector have adversely affected resources in related sectors and calls for an integrated approach to management of the environment and natural resources in a sustainable manner. The development of strong institutional mechanisms is necessary to facilitate the sustainable management of resources and to prevent further deterioration of the environment.  相似文献
