基于景观生态学的长春郊区游憩斑块结构研究

基于景观生态学理论，认为斑块是旅游活动的主要发生场所，它的空间结构决定了区域旅游的发展态势。研究了游憩斑块空间结构方面的规律，有助于深入认识斑块的宏观特征，发现旅游投资及游客流动的规律，更有助于把握斑块、廊道与基质三者的关系。从类型、等级方面详细地分析了长春郊区游憩斑块的空间结构，提出了斑块优化的理念。     

干旱河谷地区农业产业结构的调整对环境及经济的影响分析--以汉源地区为例

中国农业产业结构的调整，是中国改革开放、市场化发展的集中体现。本文以汉源地区为例，总结分析了典型的干旱河谷地带农业产业结构的调整情况，不仅促进了当地农村发展方式的根本转变、改善了农村经济、提高了农民收入，同时还解决了当地剩余劳动力的就地消化问题。本文指出了农业产业结构的调整可能对当地生态环境造成的影响，其中诸如不舍理用药用肥造成的水污染、土壤和农产品的硝酸盐污染以及土壤退化、大气污染等环境问题。需要在实践中更加审慎地调整农业产业结构。     

湖南大地景观安全规划及生态学效益分析——沿河两岸分级截流分散蓄水的治水模式

针对湖南近年来频繁发生严重水、旱灾害的实际，从综合分析湖南地质环境和水系现状入手，结合目前农村产业结构调整的方向和未来城市化进程中发展生态旅游业的需要，以优化湖南整体生态环境为目标，从大地景观安全和可持续发展的角度提出了沿河两岸分级截流分散蓄水的治水模式，详细分析了由此可能产生的景观生态学效益。     

生态工业的建立和发展

党的十五大把环境保护问题作为基本国策,并强调:“正确处理经济发展同人口、资源、环境的关系”,这表明生态问题已经引起高度重视。建立和发展生态工业已成为当前一项重要任务,本文在介绍生态工业定义的基础上,说明了建立和发展生态工业的必要性及其如何建立和发展生态工业。

Environmental changes associated with mass urban tourism and nature tourism development in Hong Kong

Hong Kong's tourism is overwhelmingly urban-focused. There is a heavy concentration of tourist and ancillary facilities in a small core urban area. A well-defined tourist business district has evolved with imprints on urban morphology. Hotels and the travel industry have limited direct environmental impacts; recent efforts have reduced energy and water consumption and waste generation. Changing preferences and market diversification call for countryside and resort types of tourism. The mainly young visitors are increasingly interested in the scenic countryside with a well-established country-park system, the tourist potential of which has been neglected. Hitherto rural excursions have been confined to 'honeypots' with little penetration away from main roads. The varied possibilities of nature tourism with ecotourism ingredients can be tapped as an adjunct to the city-based counterpart. New tourist nodes such as scattered resorts and a resort island can bring visitors close to nature. The changing patterns of consumption and the increase in rural visitorship demand measures to forestall environmental degradation.     

Eco-environmental changes and causative analysis in the source regions of the Yangtze and Yellow Rivers, China

In the most recent four decades the eco-environment in the source regions of the Yangtze and Yellow Rivers has been continuously getting worse, this is mainly manifested in the serious vegetation degradation, rapidly developing desertification, lake shrinkage and salinization, wetland degradation and biodiversity reduction. This paper attempts to give a quantitative analysis to such eco-environmental changes and explore their causes. The main factors responsible for such changes are climate change and the alterations of glacial snow accumulation and the freeze-thaw processes of the frozen soil, as well as overgrazing and rodent damage. The eco-environmental changes in the source regions not only influence the social-economic development of these regions but also have affected, or are affecting, the whole river basins' social-economic development.     

The Distribution of Tree Species in the Ridge Landscape (Southern Karelia)

The distribution of tree species in the landscape was studied using the approach based on the comparison of the ecological requirements of species and the properties of ecotopes distinguished by their position in the relief and peculiarities of basement rocks. The types and specificity of ecological regimes were determined for the typical ecotopes of the southern Karelian ridge landscape. The main environmental and successional factors determining the distribution of seven forest-forming tree species in the ecotopes of this landscape were identified. The results of this work can provide a basis for the prognosis of forest vegetation in the landscape studied.     

MEETING PUBLIC EXPECTATIONS WITH ECOLOGICAL INNOVATION IN RIPARIAN LANDSCAPES1

ABSTRACT: Appearances matter for managing riparian landscapes because the appearance of landscapes affects public willingness to accept plans and designs that improve ecological quality. Riparian landscape design and planning should respect and strategically incorporate characteristics that the public values and expects to see. Such design can be quite novel in its ecological effects, but it also should be sufficiently familiar in appearance to correspond with cultural values. This paper describes some influential cultural values for riparian landscapes and demonstrates how attention to such values supports public acceptance of ecologically innovative design in rural and urban watersheds.
