国有林权制度改革后承包户投资行为及其影响因素分析 总被引：3，自引：0，他引：3
利用黑龙江省伊春市国有林权制度改革试点林业局的195个承包户作为样本数据,分别建立承包户造林抚育投资和林下经济投资的Logistic模型,分析影响承包户后续经营行为的主要因素.研究结果表明:林权证政策、承包地立地等级和地区虚拟变量对承包户造林抚育投资和林下经济投资都有显著影响;森林经营方案政策、林地使用费政策、户主文化程度和家庭月收入等对承包户造林抚育投资有显著影响,而采伐限额政策、承包林离家距离、承包地面积、户主性别、兼业状况以及林业局木材产量等则对承包户林下经济投资有显著影响.根据对回归结果的分析,提出的政策建议是:第一,尽快完善与林权制度改革有关的配套政策;第二,发展林下经济还需要政府更多的扶持;第三,重视承包户将收取林地使用费政策与农民享受免收农业税政策进行的政策对比. 相似文献

Abstract In many countries of Africa and Asia, timber production is dominated by concession contracts in public forests. In the neo-tropics, however, timber production occurs on both public and private lands; a mixture that moves countries of the neo-tropics towards the complex systems of forestry sectors in the developed world. Therefore, much of the forest taxation and public forest management literature that currently exists is pertinent to new forest policy decisions in developing countries. Unfortunately, the similarities between forest policies in the neo-tropics and those of developed countries have largely been ignored. This paper begins the process of bridging that gap to show how existing literature is important to the design of timber concessions and accompanying policy instrument design. Although the principles we discuss here apply in any mixed harvest forest economy, we use Brazil as an example because it is in the process of adopting a system of timber concessions in national forests. In our discussion, we suggest that concessions are not a perfect substitute for private forestry in the neo-tropics; concession and other instrument policies must be designed jointly; and because concession policies and government revenue objectives may be linked, the expansion of concessions must be carefully monitored. 相似文献

Abstract Urban forest parks provide a wide range of experience outcomes to visitors. However, there is too little scientifically documented knowledge of the outcomes of the use. This study was conducted to identify visitors' psychosocial outcomes from urban forest park use, and to examine whether or not the visitors' psychosocial outcomes were related to some personal variables. Structured surveys were conducted with 2292 urban forest park visitors in six cities across South Korea during the summer and autumn of 2003. Examination of park experience outcomes revealed that there were three factors of outcomes: “learning and self/other relations”, “social and self-development” and “enjoying nature”. The results also indicated that older and more highly educated visitors were more likely to rate the outcomes as important than those who were younger and less educated. There were no significant differences in the outcomes between male and female visitors. 相似文献

Summary The Great Lakes Forest Alliance, created by charter in 1987 at the direction of the governors of Michigan, Minnesota, and Wisconsin, is a mutual aid, public/private partnership that integrates global, national and local interests by bridging the gap at a regional level. It expanded in 1997 to include Ontario. Trustees include key leaders of government and industry and citizens from a broad range of forest interests. It was designed to be as learning environment to address the resurgence of forest growth and the increasing demand for conservation, wood products and recreation. The need for the Alliance resulted in part from a perceived underrepresentation of regional forest-related issues in the national arena. The Alliance attempts to consider leading-edge strategies over the long-term in a pro-active manner, and trustees recognize the need to build respect, trust, information exchange, cooperation, coordination and collaboration among diverse interests. Among the projects that demonstrate the bridge role played by the Alliance: a regional forest resources assessment, public and private funding that supports research toward a more frequent forest inventory process, training for communities to use the collaborative learning process to address economic prosperity and environmental protection strategies and the development of sustainable forest management criteria and indicators for the region. A continual challenge is relationships among diverse forest interests across jurisdictional and institutional boundaries in a manner that promotes exchanges that build collective wisdom. 相似文献

ABSTRACTDespite the growing body of research on ecosystem services and their valuation, Jordan still faces many challenges with integration of ecosystem service concepts into forest sustainability policy and management planning. One major challenge is the incorporation of local communities into policy design, planning, and implementation. This article aims to provide information about the social value of forests’ provisioning and cultural services in a spatial context using Geographical Information Systems (GIS). The study utilizes a new approach to mapping value in rural areas by projecting local forest value from interview data. A value index is created based on indicated importance of services as well as proximity to households, permitting interpolation of value in forested areas between survey points. The resulting maps illustrate ecosystem service “hotspot” areas of significance to planning and management. This mapping technique can be applied in other locations where homes are situated near and within the ecosystems being assessed. The resulting maps serve to inform forest management policy and planning by better integrating communities’ preferences into development and conservation efforts, ensuring more efficient utilization of ecosystem services. 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

In the recent 20 years, it is a trend that forest will be distributed to villagers to manage in the world. Also in China,
“forestry three determinations” has been carried out since 1980, and many new forestry devolutions have been put forward to
and come into being. To face the fact of overusing up natural forest to result in the deterioration of ecology environment,
the strategy of natural forest protection project (NFPP) is raised after the heavy flood in 1998. Now, it is paid close attention
to systematically study to carry out the strategies of NFPP in collective forest area, especially in the community of minority
nationalities. Based on the case of forest resource management in Datu Miao Village, the experience of its forest management
in the past is analyzed and the strategies of NFPP in collective forest area are put forward.

Summary In the Panama Canal Watershed, the formulation and implementation of national park management policies has yet to realize all of the conservation, recreation, and educational goals set for the parks. We identify two underlying conditions that contribute to this breakdown in the policy process. First, national park management policies are based on the traditional United States national park model rather than on a model tailored to the unique ecological and social context of the Canal Watershed. Second, the structure and dynamics of participating institutions do not support effective decision making processes. This paper utilizes the policy science framework to provide a detailed analysis of these obstacles to effective park management and gives recommendations for improving the objectives for, decision processes concerning, and participant cooperation in national parks in the Canal Watershed. We recommend that participants initiate a prototype management program in one of the national parks in the Watershed that is easily adaptable and can be used as a demonstration site for other national park managers and participants. 相似文献
