长江口岛屿湿地的底栖动物资源研究

调查了长江口3个岛屿湿地的底栖动物资源及其生态特征和环境功能。经鉴定底栖无脊椎动物有41种,优势种为河蚬(Corbiculafluminea)、焦河蓝蛤(Potamocorbulaustulata)、缢蛏(Sinonovaculaconstricta)、麂眼螺(Rissoinasp.)、光滑狭口螺(Stenothyraglabra)、谭氏泥蟹(Ilyrplaxdeschampsi)、无齿相手蟹(Sesarmadenaani)和天津厚蟹(Helicetridenstientsinensis)。讨论了底栖动物资源的主要生态学特征及其环境功能,提出了对底栖动物资源合理利用与保护的建议。     

可持续发展与草原生态环境保护——以内蒙古草原区为例

草原具有自然和社会两方面的功能，在实现这些功能的过程中，应该遵循可持续性发展原则来维持健康的草原。草原的自然功能是社会功能的基础和保障，草原的社会功能是自然功能的延伸和发展，社会功能的发挥是建立在自然功能实现基础之上的。内蒙古地区在发展过程中要以科学发展观为指导，把建设社会主义新牧区的任务与草原发展的丰富内涵结合起来，加强草原生态环境保护，建设环境友好型和资源节约型社会。

Can Forest-protection carbon projects improve rural livelihoods? Analysis of the Noel Kempff Mercado climate action project,Bolivia

We studied the Noel KempffMercado Climate Action Project (NKMCAP),Bolivia, to assess whether forestprotection carbon (C) projects cansignificantly benefit local people. Wehypothesized that forest protection canonly securely deliver C if significantstakeholders are meaningfully andtransparently involved, traditional orcustomary rights are recognized and theirloss compensated for, and there are directlinkages between conservation anddevelopment objective. Our researchfocused on 53 members of the communities ofFlorida, Porvenir and Piso Firme and 36secondary stakeholders. In each of thevillages we held half-day meetings withcommunity leaders, complemented bysemi-structured one-hour interviews with 5,10, and 7 families, representing 20%, 10%and 8% of each community. The long-termimpact of the NKMCAP on the localcommunities may well be positive. However,in the short run, certain sections of thelocal communities are financially poorer. Forest protection projects clearly have thepotential to sequester C, protectbiodiversity and simultaneously contributeto sustainable rural development, but ifthey really are to improve rurallivelihoods, they must be designed andimplemented carefully and participatively.

Toxic metals in sewage sludge-amended soils: has promotion of beneficial use discounted the risks?

Land application of contaminated waste products has been defended as beneficial use by some scientists and regulators, based on the premise that the behavior of any toxins accumulated in soils from this practice is reasonably well understood and will not have detrimental agronomic or environmental impacts into the foreseeable future. In this review, I use the case of toxic metals in sewage sludges applied to agricultural land to illustrate that metal behavior in soils and plant uptake is difficult to generalize because it is strongly dependent on the nature of the metal, sludge, soil properties and crop. Nevertheless, permitted agricultural loadings of toxic metals from sewage sludges are typically regulated using the sole criterion of total metal loading or concentrations in soils. Several critical generalizing assumptions about the behavior of sludge-borne metals in soil-crop systems, built into the US EPA risk assessment for metals, have tended to underestimate risks and are shown not to be well justified by published research. It is argued that, in the absence of a basic understanding of metal behavior in each specific situation, a more precautionary approach to toxic metal additions to soils is warranted.     

大树杜鹃Rhododendron protistum var.giganteum和蓝果杜鹃Rhododendron cyanocarpum的濒危原因研究

大树杜鹃ＲｐｒｏｔｉｓｔｕｍｖａｒｇｉｇａｎｔｅｕｍＦｏｒｒｅｓｔｅｔＴａｇｇＣｈａｍｂｅｎｉａｉｎ和蓝果杜鹃ＲｃｙａｎｏｃａｒｐｕｍＦ．Ｗ．Ｓｍｉｔｈ被定为国家三级保护植物［１］。本文对这两种保护植物从资源调查、原产地的土壤分析、种子繁殖和贮存方式、异地保护和异地栽培条件下幼苗生长等４个方面作了濒危原因研究。研究结果表明：大树杜鹃应就地和异地保护并用，蓝果杜鹃则应采取就地保护为宜。     

中国红树林湿地资源及其保护

红树林是我国海岸湿地类型之一，自然分布于海南、广西、广东、福建、台湾等省区。现有面积约1．5万hm^2，包括26种真红树，11种半红树。中国红树林湿地直接经济价值不高，而防浪护岩、维持海岸生物多样性和渔业资源、净化水质、美化环境等生态环境功能显，属于特别容易被价值低估的海岩生态关键区。1960年代以来的毁林转海造田或盐田，毁林围塘养殖，毁林围海搞城市建设等人类不合理开发活动，使红树林面积剧减，环境恶化，红树林湿地资源濒危，急需加强管理和保护。现已建成各级红树林自然保护区18个，还需要吸收科学家积极参与，加强科学研究和宣传教育，以尽快扭转退化趋势，实现红树林湿地生态系统的恢复和可持续发展。
