A questionnaire was mailed to 351 forest supervisors in Norway about the condition and management of urban woodlands important for recreation. The overall respondense rate was 56% and included 29 large urban settlements (10,000 inhabitants) and 168 small urban settlements (200–9999 inhabitants), encompassing about 37% of the Norwegian population. The areas included in the survey cover 194,100 ha, i.e. 1.6% of the forested area. Urban woodlands were defined as the annually most frequently visited forest areas larger than 50 ha. The average size of urban woodlands was about 1000 ha, equal in large and small urban settlements. About 73% of the urban woodlands were closer than 500 m from settlements. The mean proportion of forest in the urban fringe was 40%. Like most forested land in Norway, urban woodlands were mainly privately owned. In large urban settlements the proportion of municipal forest was slightly higher than in small urban settlements. The distributions of forest stand age and tree species composition in urban woodlands did not deviate from the overall forest situation in the region. Silviculture and forest plans were prominent in urban woodlands around both large and small urban settlements, but special plans for recreation and conservation were equally rare. Recreational facilities and conflicts were most common in urban woodlands around large urban settlements. The effect of the recommendations on management of urban woodlands developed during the 1970s is questioned regarding the small differences between urban woodlands and the general forest situation, as well as between woodlands of large and small urban settlements. However, recreational efforts may have been more intensive in smaller neighbourhood woodlands of less than 50 ha, which were beyond the scope of this survey. 相似文献

根据中国2007~2011年全部A股上市公司的年报数据,从理论上分析了会计师事务所所有权规模对审计收费的影响并进行了实证检验。研究发现有限责任会计师事务所所有权规模与审计收费显著正相关,即随着事务所所有权规模的增大,审计收费也增大。研究同时发现,相对于私有产权上市公司,事务所对国有产权上市公司的盈余管理收取了更高的审计费用。 相似文献

重点国有林区森林资源产权制度研究 总被引:1,自引:0,他引:1
通过对重点国有林区森林资源产权制度变迁的分析,指出了历史上的森林资源产权制度对森工企业而言是无效率的;现行重点国有林区森林资源产权仍然是行政权利的附属品。在此基础上,分析了产权交易中的“市场失灵”和管理中的“政府失灵”问题,还分析了森林资源资产的高专用性和产权要素的复杂多样性带来的产权流转困难。最后,提出了以价值管理为核心,具有市场交易性质的、新的国有森林资源产权委托代理模式是改革的现实出路。 相似文献
