基于景观尺度的流域土地覆被变化及其水文响应

水资源短缺已成为限制华北地区社会经济发展的主要因子之一，其中山区来水减少问题已成为该区域水资源研究亟待解决的关键问题。采用景观格局分析法及统计学方法对华北土石山区典型流域--红门川流域土地/覆被变化及其水文动态响应进行分析。结果表明：(1)1990～2005年流域景观呈破碎化趋势，其中，优势景观林地在研究时段内面积变化不大；耕地、建设用地面积增加趋势显著，增幅分别为431%和444%；水域减少趋势最为明显，减幅达208%。(2)土地利用/覆被变化对流域径流有显著调节作用：随着土地结构不断优化，森林、耕地面积的增加，1998～2005年流域平均年径流系数较1990～1998年下降77%；丰、平和枯水年径流系数则分别减少64%、31%和85%；当剔除降水因素后，土地利用景观结构优化使得月径流系数减少16%～100%。(3)土地利用/覆被变化对流域径流的调节作用呈现季节性,植物生长季径流调节尤为显著     

Evaluating the Success of Conservation Actions in Safeguarding Tropical Forest Biodiversity

Abstract: We reviewed the evidence on the extent and efficacy of conservation of tropical forest biodiversity for each of the classes of conservation action defined by the new International Union for Conservation of Nature (IUCN) classification. Protected areas are the most tested conservation approach, and a number of studies show they are generally effective in slowing deforestation. There is some documentation of the extent of sustainable timber management in tropical forest, but little information on other landscape‐conservation tactics. The extent and effectiveness of ex situ species conservation is quite well known. Forty‐one tropical‐forest species now survive only in captivity. Other single‐species conservation actions are not as well documented. The potential of policy mechanisms, such as international conventions and provision of funds, to slow extinctions in tropical forests is considerable, but the effects of policy are difficult to measure. Finally, interventions to promote tropical conservation by supporting education and livelihoods, providing incentives, and furthering capacity building are all thought to be important, but their extent and effectiveness remain poorly known. For birds, the best studied taxon, the sum of such conservation actions has averted one‐fifth of the extinctions that would otherwise have occurred over the last century. Clearly, tropical forest conservation works, but more is needed, as is critical assessment of what works in what circumstances, if mass extinction is to be averted.

Coastal landscape preference evaluation: A comparison among tourists in Greece

An evaluation of coastal landscape of pine forest in Greece by summer visitors of various nationalities was carried out. The visual preferences for a set of landscape, represented in photographs, expressed by these various nationality groups were compared. The subjects used in this research came from Greece, Germany, Italy, France, Great Britain, Austria, Yugoslavia, and Scandinavian countries. The findings show that there is an agreement over the basic preference, but, nevertheless, there are differences of opinion between the nationality groups that might be attributed to cultural influences and the effect of being familiar with their own environments. Since coastal landscape plays an important role in the tourist industry, these findings could be very useful to policy-making agencies.     

Habitat, Landscape and Bird Composition in Mountain Forest Fragments

The study attempts to separate the effects of forest fragmentation related to landscape (patch area, isolation) and habitat (altitude, vegetation structure) on bird community composition in a mountain pine forest. Bird composition was related, using a multivariate approach (canonical correspondence analyses), to either habitat or to landscape, eliminating the effect of habitat statistically. Bird composition and species richness varied with patch area and isolation from large pine stands, but this effect could be assigned principally to variation in vegetation structure and altitude. Another effect, that of increasing occurrence and numbers of Anthus trivialis with decreasing distance to nearest low-altitude forest, could be assigned to both habitat (grass cover) and landscape (connectivity effects). Management implications are drawn from the results.     

景观生态学在建设项目生态环境影响评价中的应用

公众参与市容环境规划与管理的方法设计--以南京市的实践为例

市容环境是与公众生活联系最为紧密的领域,也是公众参与最容易进行的领域。南京的城市建设要实现“经济发达、环境优美、融古都特色和现代文明于一体的现代化江滨城市”的目标,公众参与市容环境的规划与管理是关键内容之一。论文以“南京市市容环境卫生发展规划”项目工作为基础,分析和阐述公众参与的内涵,提出公众参与市容环境的五大步骤,并针对南京市容环境方面的具体案例,设计出符合南京特色的公众参与市容环境规划与管理的方法框架模型,包括决策模式、制度框架的共管体系。     

阜康市生态旅游规划研究

生态旅游规划是生态示范区规划的重要组成部分。本文以天池风景区规划为例阐述生态旅游规划应突破以风景区为主单一的旅游景观格局,应根据景观生态学原理、旅游地理学和旅游经济学理论,按照景观格局的梯度性变化为依据,以增长旅游线路、丰富景区类型、提高旅游收入为内容,以保护景区资源、开发景区资源为目标,开展基于发展“大旅游”思想的以沈域为单元的全面战略性规划,为实现阜康产业结构调整、增强区域经济实力提供依据。
