Home range and habitat composition of male Reeves's Pheasants in an agricultural-forest plantation landscape in central China:a preliminary report被引量:2
2011年
We present a preliminary examination of the home range and habitat use of male Reeves's Pheasants (Syrmaticus reevesii) in an agricultural-forest plantation landscape on the Xianjuding Forest Farm, Hubei Province, central China. Fieldwork was carried out from March to August in 2003. The home range of males averaged 33.17 ± 12.55 ha by MCP (minimum convex polygon) and 21.05 ± 5.61 ha by a 95% fixed kernel estimator. The core area by a 60% fixed kernel estimator was 3.92 ± 0.27 ha. We did not detect significant seasonal variations in home range, core area and movement in this farm. Chinese fir (Cunninghamia lanceolata) plantations were the dominant habitat type within the home ranges and core areas. The males used their habitat non-randomly in spring and summer, preferred the fir plantations and avoided broadleaf forests in both seasons. In addition, the males used shrubs less than were available in the spring. The vegetation structure of different habitats may be the leading factor affecting the use of the habitats.

中国自然保护区管理能力现状调查与分析被引量:26
2011年
为了解中国自然保护区管理现状、发现存在的不足,并为有关政策和措施的制定提供科学依据,在问卷调查的基础上,结合专家咨询和实地考察,对中国自然保护区管理能力进行了调查和分析。调查内容包括:自然保护区的基本特征、管理机构与人员及人事激励与人员培训、土地权属、日常管理制度与管理条例、公安机构建设与执法权限、保护目标和总体规划、资源调查与监测、对外合作与宣传教育、资金保障、设施设备及社区管理等方面。结果表明:中国自然保护区管理能力在机构建设、人员配备、土地权属管理、资源管护执法权限、资金投入、资源本底、科研宣教、社区管理等方面均存在不足。建议进一步加大宣传教育的力度和科学性,提高社会各界对自然保护区事业的认识和支持,各级政府要承担起发展自然保护区事业的责任,大力支持,各方共同参与,采取有效措施解决这些不足,从而推动我国自然保护区建设管理水平的整体提升。

自然保护区面积与野生动物空间需求研究进展被引量:7
2010年
自然保护区面积的大小可能对野生动物种群生存产生影响,也给自然保护区管理带来困难。由于我国自然保护区面积规划还没有一个十分可行的依据,迫切需要对如何科学确定自然保护区面积的问题进行研究,如今这也成为我国自然保护区建设与管理研究中一个重要问题。文中简要回顾了自然保护区面积确定的研究进展,分析了自然保护区面积与野生动物空间需求的关系;归纳总结了野生动物的空间需求及其类型,并分析了影响不同类型需求空间的因子和确定方法;最后,根据我国自然保护区面积的现状,提出了依据保护目标种实际需要的空间大小来确定野生动物类自然保护区面积的方法,以期为自然保护区面积的确定提供参考依据。

我国自然保护区集体林现状与问题分析被引量:14
2011年
文中从全国198个自然保护区以及东南五省43个森林和野生动植物类型国家级自然保护区等3个层次全面阐述我国自然保护区集体林现状,从历史上对土地权属问题的淡化或忽视、法律法规不足、当地社会经济发展与自然保护的矛盾及补偿机制等方面分析了我国自然保护区集体林权改革中存在的问题,并结合国外自然保护区土地权属管理的成熟做法,提出了加强试点、科学规划、完善法律法规及政策体系、创新模式、充分尊重社区群众的利益、完善生态补偿机制等对策,以推动我国自然保护区集体林改工作,促进自然保护区与社区和谐发展。

Breeding Habitat Selection of Reeves’s Pheasant (Syrmaticus reevesii) in Dongzhai National Nature Reserve, Henan Province, China被引量:7
2010年
Reeves's Pheasant (Syrmaticus reevesii) is a threatened pheasant species endemic to China. The habitat use of territorial male birds was surveyed by the help of live decoys in a core area of Dongzhai NationaI Nature Reserve. The breeding habitat selection of this pheasant was examined at two scales (115 m and 250 m scale, i.e. 4.15 hm^2 and 19.63 hm^2, respectively), including the characteristics at distance scale. Investigation was based on line transect, RS and GIS in Dongzhai National Natural Reserve from 2001 to 2003. Moreover, a range of habitat variables were compared between used and control points at each scale, and stepwise logistic regression was applied to select the key scale and the key habitat factors in relation to breeding habitat selection of this bird. Our results stated that the territorial males at Baiyun occurred mostly in mixed forests, followed by fir forests, pine forests, shrubs, and broadleaf forests. The area of conifer forests was the key factor influencing habitat selection of this bird in breeding period at the scales of 115 m and 250 m, and the proximity of farmland was important for habitat selection in breeding seasons. Furthermore, Reeves's Pheasants attached great importance to the scale of 115 m. When considering a range of habitat variables at all scales within a multivariate regression, the leading factors having effect on habitat selection in the breeding period were areas of conifer forests at 115 m scale and the distance to farmland. In addition, these above results suggested that strengthening the management of suitable habitat, and optimizing the habitat configuration are important in promoting conservation of this bird. However, it also highlighted the importance of initiating future researches on the conifer forests and their impact on the population of Reeves's Pheasants, which would be beneficial to promote the habitat conservation of this pheasant more effectively.
