<正>以紫金山国家级森林公园为研究对象，以遥感图像处理与地理信息系统软件ERDAS 8.7、ArcGis 9.0为空间分析平台，分别选取研究地区2000年IKNOS、2002年SPOT5、2004QuickBird3种不同时期的遥感数据，在监督分类的基础上进行邻域分析，构建风景林未来10年发展的情境。从景观空间格局和景观资源保护目标两个方面对多情境规划方案进行评价，并制定了风景林的优化情境规划。研究表明：与研究地区2002年的景观结构相比，优化情境规划方案中农地完全消失，阔叶林、企业机关用地、旅游服务设施用地所占比重分别下降了18.48％、2.30％、2.85％，而针叶林、园林绿地、混交林的比例分别上升了13.26％、14.81％、4.47％，从而提高了森林公园风景林四季的美景度，满足了风景旅游、森林培育、市民休闲、生物多样性保护的多种需求。

In order to estimate poplar biomass by using forest inventory of poplar planting trees, while applying software SPSS12.0, according to collected materials of 23 sample trees of I-72 Poplar biomass in wuzhi county, the allometric equation has been designed to estimate poplar biomass. Biomass Expansion Factor (BEF) function and the ratio of the weight of the root to the weight of the shoot (RSR) function of stand description factors were established by forest inventory and allometric equation and then the total stand biomass was computed according to the growing stock and basic wood density. The results of function curve estimation show that BEF and RSR have very good relevance to stand average height, basal area, stand age and stand volume, and the value of BEF is about 1.3 and the value of RSR range from 0.14 to 0.6,and reduces with the value of forest inventory increases. The study could offer a quality basis for using forest inventory of poplar planting trees to estimate poplar biomass.
