该文以黑龙江五营林区为主要对象 ,通过对阔叶红松林及其次生类型结构特征和动态变化的分析 ,研究退化生态系统的恢复途径和可持续经营措施 .阔叶红松林是小兴安岭地区最典型和最稳定的植被类型 ,但其面积和蓄积都在迅速减少 ,显著的特性是通过优势树种红松的世代更替及其与阔叶树种的相互更替 ,维持群落的周期性波动和稳定结构 ,经营上应采取保护措施 .硬阔叶林是阔叶红松林破坏后所形成的次生林 ,在一些地区成为杨桦林向阔叶红松林恢复的中间途径 ,具有广泛的代表性 .次生硬阔叶林稳定性小 ,尤其是那些由硬阔叶树形成的纯林更是生长速度慢 ,更新不良 ,结构不合理 ,必须采取有效的恢复途径 ,减缓退化 ,实现可持续经营 .杨桦林是最典型的次生软阔叶林 ,具有十分广泛的分布 .杨树和桦树都是生长速度快的强阳性树种 ,阔叶红松林一经破坏 ,它们首先占据采伐和火烧迹地 ,迅速成林 .然而 ,这些树种材质不良 ,群落结构单一 ,生产力低下 ,极易被其它树种所代替 ,所以要迅速调整杨桦林结构 ,采取恢复和重建措施 ,发展阔叶红松林 .至于非地带性植被云冷杉林和落叶松林等采取维持措施 ,保证生态系统的稳定与平衡 Based on the analysis of the structural characteristics and dynamic changes of Korean pine forest and its secondary types, this paper studies the ways of restoration of degraded ecosystems and measures of sustainable management. The broad-leaved Korean pine forest is a part of Xiaoxing’anling The most typical and the most stable types of vegetation, but its area and accumulation are rapidly reduced, the remarkable characteristic is through the replacement of the dominant species of Korean pine and its replacement with broad-leaved species to maintain the cyclical fluctuations and stable structure of the community, Management should take protective measures.Hardness hardwood broadleaved forest is a secondary forest after the destruction of broad-leaved Korean pine forest, in some areas as birch forest to the broad-leaved Korean pine forest restoration of the middle way, with a wide range of representative. The small, especially the pure forests formed by hard broad-leaved trees are slow growth, poor regeneration and irrational structure, and must take effective recovery path to slow down the degradation and achieve sustainable management.Yang birulin is the most typical secondary soft broad Ye Lin, with a very wide distribution of poplar and birch are strong positive growth of fast-growing species, broad-leaved Korean pine forest once destroyed However, these species are poor in material, single community and low productivity, and are easily replaced by other species. Therefore, the structure of poplar forest should be promptly adjusted and recovery and reconstruction measures should be taken to develop a broad Yehsong pine forest. As for non-zonal vegetation such as fir and larch forests and other maintenance measures taken to ensure the stability and balance of the ecosystem
