连云港南云台林场森林可持续经营技术探讨

Discussion on forest sustainable management technology of Nanyuntai Forest Farm,Lianyungang

依据森林功能区划施策导则和连云港云台山区生态系统聚类特征,该文以培育有连云港地域特色的近自然复层异龄混交恒续林为目标,提出南云台林区森林可持续经营的技术原则;通过对现处于不同演替阶段的各类公益林配套组装已被实践检验,且富有成效的近自然可持续目标诱导经营措施,探索了该林区以实现树种组成乡土化、林分结构多层化、综合功能最大化和“恒续覆盖持续利用”为导向的森林可持续经营技术模式;分析并试图解决在森林多功能经营中,如何既能突出森林主导功能,又能协调多目标冲突的关键技术难点。共设计出了若干种人工近自然林演变为恒续林的经营模式,和典型林分可预期诱导技术方法。上述模式与方法对诱导构建具有连云港特色的物种多样、功能完备、健康高效、景观优美的森林生态系统,精准提升连云港云台山森林质量,保障森林发挥综合效益、恒续利用与稳定发展具有技术支撑和参考作用。

Based on the ecological function zoning and clustering characteristics of forest ecosystem in Yuntaishan District of Lianyungang,the key technical difficulties of how to highlight the leading function of forest and coordinate multi-objective conflicts in multi-functional forest management were analyzed and solved.Aiming to cultivate near-natural multi-layer mixed perennial forest characteristic of Lianyungang region,the technical principles of sustainable management in Nanyuntai forest area were put forward.And for near-natural sustainable goal,with the measures having been tested by practice and fruitful in assembling various public welfare forests in different succession stages,the technical model of sustainable management in this area was probed to realize the localization of tree species composition,multi-layer stand structure,maximization of comprehensive function and guidance of“continuous coverage and sustainable utilization”.Furthermore,management modes relative to dozens of artificial near-natural forests altering into continuous forests were designed,and several predictable induction techniques of typical stands put forward.They should refer to inducing the construction of forest ecosystem characteristic of Lianyungang region,for example,diverse species,complete functions,health,efficient and beautiful landscape,and improving accurately the forest quality of Yuntai Mountain in Lianyungang,ensuring the comprehensive benefits,sustainable utilization and stable development of the forest.
