辽西地区水土保持林合理经营技术及可持续发展理论初探

Preliminary Discussion on Reasonable Management and Persistent Development of Soil and Water Conservation Forest in Liaoning West Districts

通过对辽西地区水土保持林发展过程的回顾,总结出辽西地区现有水土保持林存在的主要问题,即树种结构简单;林分生产力低;多样性指数低等。根据辽西地区现有水土保持林特点,尽大发挥其效益并持续时间长,且在林木更新时效益不间断,即水土保持林各种效益,尤其是森林防护效益的持续利用等,确立了现有水土保持林合理经营利用的最高目标,提出了辽西地区水土保持林的合理经营技术。从可持续发展经营的角度出发,由森林可持续经营的概念、结合森林等级理论以及相关生态学理论,确定了森林可持续经营的目标和经营技术。

The author looked back the development process of soil and water conservation forest in Liaoning west districts, and summarized that the main problems at present are： the composition of the tree species is too simple, the productivity of the forest is low, the diversity index is low,etc. The author put forward the reasonable management technology in Liaoning west districts, which included that according to the characteristic of the soil and water conservation rorest at present, benefit the most from it and keep benefiting from it as far as possible, and don＇t disconnect it during the woods＇ renewing. That is, benefiting continuously from the management of the soil and water conservation forest, especially from the forest protection. The author also bring forward the highest goal for reasonable management of the present soil and water conservation forest. From the point of persistent development, combine the forest grade and relative ecological theory, develop forest persistent development goal and management technology.
