徐州山地森林生态质量评价研究

Ecological evaluation of forestry quality in Xuzhou mountainous

利用徐州山地森林标准地调查数据,从森林结构与功能和森林健康状况2个方面来构建森林生态质量评价指标体系,采用层次分析法、等级评分法、加权综合指数法来评价徐州山地森林生态质量状况。结果表明:无论是森林结构与功能还是健康状况,森林生态质量都是天然林好于混交林,混交林好于人工林;徐州山地森林生态质量等级好、中、差所占的比重大小悬殊,其中质量等级为差的所占比重最大,说明了徐州山地提高森林生态质量还有很大的潜力。

Our paper propounded a suit of forest ecological quality evaluation system by structure, function, and healthy conditions of forest, based on the forestry stand investigation in the mountainous area in Xuzhou. The forest ecological quality of mountainous regions in Xuzhou was evaluated through the methods of AHP, ecological elements quality scale marking and the weighed averages composite quality index. The results were as follows ： 1 ） The forest quality （ forest structure, functions, the forest health） ranked the natural forest 〉 the mixed forest 〉 the Plantation ; 2） There were great potentials to improve the forest quality in Xuzhou for the proportions of three forest ecological quality grades were very lopsided.
