Environmentally acceptable and economical forest operations are needed for sustainable management of forest resources. Improved methods for harvesting and transporting timber are especially needed for wet sites. As the demand for hardwood lumber continues to increase, improved and alternative methods are needed to ensure acceptance of timber harvesting for the wet site conditions that are typical of bottomland hardwoods. Some alternative technological developments include grapple saw feller-bunchers, wide tires, larger forwarders, clambunk skidders, two-stage hauling, mats, cable systems, helicopters and towed vehicles and air-cushioned vehicles. These developments have the potential to improve the performance of the harvesting system and to reduce the negative effects of conventional operations on conventional sites and on difficult sites such as wet areas. Although many of these new alternatives are now operational, others are just concepts or evolving prototypes. More research is still needed to optimize these alternative technologies and to reduce costs associated with their implementation. 相似文献

Summary Ecotourism has been used successfully in many countries to promote economic well-being, conserve natural resources, and promote community development. A thorough examination of the factors that make a successful and unsuccessful ecotourism program was conducted in this paper. This analysis was performed in order to formulate recommendations for the development of an ecotourism program in the Panama Canal Watershed that will meet these objectives. A careful look at the conservation of natural areas, community development, and the economics of ecotourism fleshed out the good and the bad of existing programs. Case studies from other developing countries were used in order to set up criteria that should be used in Panama's blossoming ecotourism industry. Panama has a vast array of natural and cultural resources that can benefit from a carefully planned ecotourism program. When planning this initiative it is very important to take the politics of the country and communities into consideration, make sure the project is scaled to the carrying capacity of the natural resources and community involved, use existing infrastructure, train a skilled local work force, and maintain monitoring programs that ensure that an unsuccessful program be either improved or terminated. 相似文献

Conservation and restoration of degraded ecosystems in arid and semi-arid areas of northwest China 总被引:1,自引:0,他引:1
In “West Development” of China, one of the most important activities is the Natural Forest Protection Program, designed to
swiftly convert the focus of management and utilization of the natural forests from a timber orientation towards forest conservation,
sustainable management and environmental protection. The project covered almost all the arid and semi-arid regions in Northwest
region. Accompanying this great campaign this paper studied the conservation and restoration model of degraded ecosystems
in arid and semi-arid lands in Northwest China. The past practices have resulted in considerably natural forest degradation
and loss through land conversion (primarily for agriculture), over-harvesting, inadequate reforestation and lack of protection.
The consequences have been the loss of soil and water resources, diminished timber production capacity on a sustainable basis,
and environmental losses. This paper applied Aronson’s restoration model and proposed the conservation, restoration, re-allocation
and preservation program for the implementation of environmental improvement and natural forest conservation. 相似文献

石灰岩喀斯特地貌在东南亚地区的经济活动中具重要的地位,其生物多样性保育与文化遗产价值更是弥足珍贵.越南的喀斯特地区正好是当中的写照,区内观光景点林立,亦有不少世界遗产地区、植物多样性的全球中心及多个具有国际保育重要价值的地点.尽管喀斯特生态系统在越南的保护区系统内占一定数量,可是一连串活动如采矿、土地开垦、基建发展,都对水文或栖息地做成严重干扰;另外野生动物的偷猎及非法砍伐等各种消耗森林资源的活动,都日益威胁整个喀斯特生态系统.因此,喀斯特地区已成为野生动植物保护国际(FFI)的重点保育对象.下文将会略谈越南喀斯特生态系统现正面临的威胁,继而介绍现时FFI在四个主题领域上利用的若干保育手法:(1)景观地貌层面上的管理;(2)社区参与保育;(3)生态旅游及保育关系(4)从文化着手的保育方法. 相似文献
