坐落于滇池南部的云南晋宁南滇池国家湿地公园是昆明唯一的国家湿地公园,本文从南滇池湿地公园的五大功能分区(湿地保育区、合理利用区、宣教展示区、湿地恢复重建区、管理服务区)探讨了其湿地景观,并倡导了南滇池湿地公园的健康理念。公园的南滇池沙滩将湿地与旅游完美结合,水生花卉、蔬菜浮床培育种植创造了湿地公园合理利用新模式。南滇池湿地公园作为国家湿地公园,其功能分区的设置、湿地合理利用模式的开发、对湿地科普宣教功能的重视以及健康理念与湿地景观的融合,对于其他湿地公园的建设是具有参考和借鉴价值的。 相似文献

There is much debate about the way conservation and development are best integrated to reduce the encroachment pressures of poor rural communities on the biodiversity resources of protected areas in the tropics. One frequently recommended instrument is to intensify farming systems in the adjacent areas, so as to decrease the need to harvest resources from national parks. This study examined this issue by analyzing the effects of different household land uses in villages near a national park on their propensity to harvest resources from the park. In the northern part of the Kerinci Seblat National Park (Sumatra Island, Indonesia) the park buffer zone is comprised largely of community or village forests and human settlements. The village forests were formerly managed as production forests and provided significant cash income to the village. They were converted into farmland, particularly to mixed-tree gardens or agroforests. Natural forest coverage has now declined to 10% of the former area within village forest land. We analyzed the characteristics of the mixed gardens and village forests, and their practical contribution to reducing farmers' dependence on the adjacent national park resources. Households with farms that were more diversified were found to have much less dependency on the national park resources. Households that farmed only wetland rice fields registered the highest value of forest products obtained from inside the park. Households that farmed only mixed gardens had an intermediate level of park resource extraction, while those that had farms composed of both components (i.e. wetland rice fields and mixed gardens) had a dramatically lower level of economic dependency on park resources than households in either of the other two categories.This revised version was published online in November 2005 with corrections to the Cover Date. 相似文献

利用昆明市1990年和2000年2期遥感影像解译数据,结合GIS和统计软件,对昆明市10年间景观格局变化特征进行分析.结果表明:1990~2000年昆明市各景观要素之间变化显著,景观要素面积增加的有建设用地、城镇居住用地、草地和旱地,增加最大的是城镇居住用地,增加了10.92 km2,比1990年增加了5.5%;面积减少的有水田、林地和湿地;各景观要素之间相互转化,其主要特征:①城区外水田、旱地等生产用地向城市居住用地和建设用地转移,其中水田在10年间向城镇居住用地转化了1 134.25 hm2,占1990年水田的5.81%;②林地、旱地和草地之间相互转化,林地向草地转化的面积最大,为1 694.19 hm2.对昆明市景观格局分析结果为,随着城市化的快速发展,城市居住用地景观破碎度减少,斑块形状趋于规则化;林地、草地和旱地景观破碎度增大、斑块形状复杂化;景观总体格局趋向于多样化、复杂化. 相似文献
