Environmental services and landscape goods are rarely incorporated into economic valuation of natural resources, even though these resources may constitute a large proportion of the total ecosystem value, mainly in natural protected areas. The frequent occurrence of wildfires in Spanish protected areas requires a tool, which allows for the comprehensive management of landscape resource and mitigating the potential economic impacts caused by fire. In this paper, we extend the economic valuation theory to the concept of economic vulnerability. Geographic Information System was used to develop a framework for landscape impact assessment using annual landscape value, vegetation resilience and fire behavior. An economic approach of landscape susceptibility was provided by the integration of these three components. Once landscape susceptibility had been spatially characterized, landscape vulnerability was analyzed from criteria associated with landscape susceptibility and burn probability. There was a notable variation in landscape vulnerability ranging from 412,000 Euros to 1,200,000 Euros in Aracena Natural Park (186,828 ha) according to the selected contingent valuation scenario. The availability of cartography of landscape vulnerability could play a critical role in budget optimization and the decision-making process. In this sense, this approach helps managers to identify different efforts according to spatial distribution of the risk and fuel management strategies to increase economic efficiency of fire prevention activities.

贮木场空间管理系统的初步研究 总被引：1，自引：0，他引：1
传统的贮木场木材信息管理仅限于产、销、存等基本的功能,本文研究的贮木场空间管理系统是在传统的贮木场管理系统基础上,通过对贮木场平面图道路、楞区的划分以及合理地划分楞位大小。采用可视化图形方式对楞位和楞位中存放的木材进行管理,以提高贮木场楞区空间利用率,简化仓储业务操作,实现高效直观的贮木场仓储管理。 相似文献

Mountain forest management is, and has always been, multipurpose-oriented. It should provide for private goods, such as timber, as well as public goods, such as protection against natural forces. This paper investigates private, state and common property regimes in terms of theoretical managerial performance, since empirical studies are scarcely available. Private property rights are sufficient for the production of private goods, whereas public goods have to be safeguarded by state intervention. The performance of state property regimes depends on objectives set by society and their implementation by public officials. Whereas state intervention in private and public property regimes in mountain forests is a necessary condition for multipurpose forest management, common property regimes would be less dependent on it. Usually, the rights holders of common property regimes use mountain forests for the production of both private and public goods. One can conclude that common property regimes are promising for the multipurpose management of mountain forests. In practice, however, common forest property regimes in Switzerland and Austria have become very dependent on public support. Research is recommended in order to investigate into the underlying reasons. 相似文献

通过对"永林公司"不同森林经营模式下水源涵养功能的比较研究,结果表明:不同经营模式林冠层的水源涵养能力都大于灌草层,部分枯枝落叶层大于林冠层。其中,林冠层持水量最大的为采育结合模式,持水量高达16.7461t/hm2,封禁保护模式和生态功效模式林冠层持水量也较高,均在10t/hm2之上。相比之下,保育补植模式林冠层持水量最小,仅有1.8334 t/hm2;灌木层持水量最大的是块状利用模式,为5.4354t/hm2;最小的是采育结合模式,为0.1346 t/hm2。其他经营模式的持水量大小相差不大,在0.2-0.4 t/hm2之间;枯枝落叶层的生物量大致在5-17 t/hm2范围内,其中持水量最高的为改良增效模式,达到16.2668 t/hm2;其它依次为保育补植模式、封禁保护模式、间伐调整模式、生态功效模式、定向培育模式、集约经营模式、采育结合模式、块状利用模式;另外,各种经营模式土壤的贮水能力大小顺序为生态功效模式改良增效模式采育结合模式集约经营模式封禁保护模式块状利用模式定向培育模式间伐调整模式保育补植模式;各种经营模式中土壤渗透能力比较好的有间伐调整模式和采育结合模式,而改良增效模式、定向培育模式和集约经营模式的渗透能力比较差。 相似文献

Sustainable forest management is the process of managing forest to achieve one or more clearly specified objectives without diminishing the forest’s ability to continue providing goods and services in perpetuity. In this paper, we show how the African Timber Organization/International Tropical Timber Organization principles, criteria and indicators for the sustainable management of African forests can help timber companies assess their progress towards this goal in Gabon. Through a partnership between International Tropical Timber Organization project PD 124/01 Rev. 2(M), the World Wildlife Fund, and the ministry responsible for forests in Gabon, audits were conducted between 2012 and 2014 to evaluate the implementation of sustainable forest management in 14 forest concessions in Gabon. In general, results show that Principle 4, linked to the well-being of workers and local populations, proved the most difficult principle to implement, while Principle 3, dealing with maintaining ecological functions, was the least problematic. A number of companies were found to be experiencing significant difficulties in implementing management plans. It is also clear that independent forest certification has become a key element for ensuring the successful implementation of sustainable forest management. 相似文献
