| 摘 要： | 森林资源资产存量变化核算是建立森林资源资产管理绩效考核制度、遏制森林资源资产流失的必要前提与基础。在基于3S技术构建区域森林资源资产存量变化核算方案的基础上,对2000—2010年北京市森林资源资产存量数量、质量及其变化展开核算与分析。结果显示:在数量方面,除落叶阔叶林减少以外,其余各类森林数量都有不同程度增加,其中平谷区、顺义区果园林与海淀区、朝阳区城市绿地森林以及密云县、延庆县、门头沟区的落叶阔叶灌木林增幅最为显著;在质量方面,森林资源资产综合质量差、中2种等级森林面积都呈小幅减少趋势,质优森林面积大幅增加,其中平谷区、密云县增加最为显著;总体而言,2000—2010年间北京市森林资源资产存量数量大面积增加、森林质量大幅度提高,总体呈累积增加态势。

| Abstract: | The accounting and analysis of stock assets change of forest resource is the prerequisite and basis to establish the appraisal system of the forest resources assets management performance and to curb the loss of forest resource assets. The 3S technologies were adopted to construct the accounting scheme of regional stock assets change of forest resource, and the quantity, quality and change of the stock assets of forest resource in Beijing from 2000 to 2010 accounted and analyzed accordingly. The results showed that in terms of quantity, all types of forests except deciduous forest had increased to various extents, among which the fruits forest in Pinggu and Shunyi counties, the garden forest in Haidian and Chaoyang districts, and the deciduous broad-leaved shrub forest in Miyun County, Yanqing County and Mentougou District had the most obvious increase. In terms of forest quality, the area of superior quality forest had risen considerably while that of the poor and medium-quality forest decreased slightly, among which Pinggu & Miyun counties increased most remarkably. Overall, between 2000 and 2010, the quantity of forest resource assets in Beijing had increased and the quality greatly improved greatly, in a general trend of accumulative increase. |
