中文摘要：

提升森林的生态服务功能已经成为当前生态文明建设中森林经营的重要目标。本文以江苏省溧水林场4种典型北亚热带次生森林群落为研究对象,利用FORET模型分别对自然状态下与人工抚育条件下的森林动态过程开展模拟研究。通过比较实施抚育措施前后物种重要值和群落生物量的变化,对不同森林抚育措施的效果进行评价。模型模拟结果显示,对于组成接近地带性植被的麻栎（Quercus acutissima）＋栓皮栎（Q.variabilis）群落,常用抚育措施下森林群落组成结构的变化与其自然演替相比并无明显差异;而对于处于演替早期阶段的马尾松（Pinus massoniana）＋白栎（Q.fabri）群落、冬青（Ilex chinensis）＋马尾松群落和麻栎＋马尾松群落,综合实施透光伐、补植和除伐等抚育措施有利于其向地带性植物群落的快速演替,同时可促进群落的生物量累积。本研究表明,林隙模型在森林经营辅助决策方面具有潜在的应用价值,可成为森林抚育效果定量评估的有用工具。

英文摘要：

Improving forest ecosystem services has become one of the most important aims of forest management in the context of current ecological civilization construction. In this paper, four typical subtropical secondary forest communities in Lishui Forest Farm, Jiangsu Province were selected as the study objects. We used the FORET model to simulate forest dynamics of these communities under the natural state and artificial management. By comparing the changes before and after the implementation of management measures in species importance value and total biomass of the stand, we evaluated the effects of different tending management measures. For the Quercus acutissima＋Q. variabilis community, there was no obvious difference in changes of forest community composition and structure between under conventional tending measures and in natural development. For the Pinus massoniana＋Q. fabri community, Ilex chinensis＋P. massoniana community and Q. acutissima＋P. massoniana community, which were at relatively early succession stages, comprehensive measures, including released thinning, replanting, and clean cutting, sped up the community succession, and promoted the accumulation of stand biomass. Our results suggested that the forest gap model had a potential application value in the decisionmaking of forest management, and it may be a useful tool for quantitative assessment of forest management effect.
