Despite its evident abundance and endemism, however, the biodiversity is faced with threats of ecological fragility and human disturbances in socioeconomic development resulting in attenuation of biodiversity, degradation of ecosystems and serious loss of species, thus, it needs to be carefully studied for its sustainability. Based on the analyses of the geographical diversity, the macro material bases of Yunnan＇s biodiversity were reviewed and six characteristics of the provincial biodiversity were described in the ecosystems, forest types, species compositions, endemic species, genetic resources, etc. By appraising the present status of the provincial biodiversity conservation, the facts that the biodiversity coexisted with fragility were revealed so that eight key disadvantageous factors in the provincial ecological fragility causing serious biodiversity loss were summarized and described in this paper. In order to satisfy the two-fold needs of biodiversity sustainability and socioeconomic development, eight strategies for the sustainable development were intensively elaborated by borrowing certain theories in modern conservation biology, recycling economics and some successful innovations, and by giving comprehensive consideration to the ecological fragility mechanism, nature reserve construction, environmental protection and the exploitability of resources for biodiversity sustainability and socioeconomic development. Accordingly, relevant targets, principles, tactics and measures for effective biodiversity conservation and sustainability were suggested to lay a solid theoretical foundation and reliable scientific basis for the biodiversity and socioeconomic sustainable development.展开更多

Recommendations for the protection of vegetation on and around the site, including control of the erosion and run off from the construction site were proposed and implemented, resulting in effective protection of the local vegetation cover. Stream macrobenthos were low in species diversity and abundance and did not show a changing trend during the construction and the operation of the land fill. Birds attracted to the active dumping site were dominated by Crested Mynah Acridotheres cristatellus and the Tree Sparrow Passer montanus. After an increase in the population during the warmer months, the number of birds seen on the land fill site decreased to 10 in December 1994. Mammal monitoring by live trapping revealed that the rat population did not increase after the land fill operation started. This project was the first comprehensive’ ecological study and monitoring of an urban land fill in Hong Kong and it demonstrated that careful environmental planning and implementation of mitigation measures can successfully limit environmental impacts of landfills to acceptable levels.展开更多
