增加种源树种促进侧柏林演替技术及短期效果

Succession of Platycladus orientalis Forests Promoted by Supplementary Planting of Native Tree Species and Its Short-term Effect

根据徐州市云龙山侧柏林的现状及社会发展需要,制订了人工促进侧柏纯林演替的目标、原则,确定了间伐抚育和林窗开设的标准,提出了种源树种及其配置方式和栽植、管护技术方案。林分改造后各树种生长良好,植物多样性显著增加,景观质量明显改善,风景林的效能已初步形成。

The goals and principles of promoting the succession of Platycladus orientalis forests were given based on the actuality of P.orientalis forests and the need for social development.The standards for intermediate cutting and tending as well as the forest gap opening in the forest were determined.Moreover,the planting and management of native tree species and their allocation modes were also put forward.All the tree species grew well and the plant diversity increased after the forest alteration.The landscape quality was obviously improved,and an aesthetic value of the forest had begun to take shape.
