论生态环境对综合国力的影响被引量:3
2002年
生态环境是一种不可替代的资本 ,良好的生态环境是一个国家获得健康、稳定发展的基础 ;生态环境具有重大的直接经济贡献能力和重要的潜在价值 ,它作为一种资本及其所具有的价值 ,不仅是一个国家存在的基础 ,也是一个国家实现发展的依托和基本条件。对于人口众多、经济发展仍然受到自然资源制约和限制的中国来说 ,改善和保护生态环境是发展综合国力的途径。

游客信息与湖泊旅游风景区开发中的生态建设——以云南抚仙湖为例被引量:3
2000年
valid survey tables from 700 inquired tourists were harvested in the newly-opened scenic spot of Lake Fuxianhu in the middle of Yunnan Province of China, and the feature of ages, profession, cultural structure, the tourist distribution in the scenic spot around year, the preference and interests, expenditure, the attitude of facilities allocation, satisfaction level in tourism service were analyzed. Following are some conclusion to be drawn from this study: tourist in Lake Fuxianhu mainly swarmed in the season of summer and spring so that in this rush season there was not much tourism facilities and services available for tourists and no due expenses from them; less tourism items and activities than needed in the scenic area were given to the tourists so that the staying time was short and the income of tourism was low; the water quality was vital to the tourism development in the lake. From the view of the macroscopic ecological economics, some countermeasures were put forward about the rational development and protection in the lake: a lot of new tourism spots located around the hills or some other areas near the waters in replacement of that around the lake should be constructed and new tourism items should be conducted so as to prolong the staying time of the tourists, raise local income and alleviate the load of water environment; the distinctiveness in Lake Fuxianhu should be built up in the process of the exploitation of tourism in coordination with the natural environmental landscape and humane feature; it is of great importance to protect and build up the vision corridor around the lake; the development of phosphors resource in the watershed of the lake and protection of the lake should be harmonized.

植被恢复措施对退化生态系统土壤酶活性及肥力的影响被引量:115
2002年
对于退化生态系统的恢复,首先是植被恢复,植被恢复是充分利用土壤-植物复合系统的功能改善局部环境,促进生物物种多样性的形成。植被恢复的生态效应不但影响林地本身,也影响周围的环境,进而对区域和全球的生态平衡有所贡献,因此。
