Abstract

According to the characteristics of Zhanggutai sandy land, the regeneration and transformation of Pinus sylvestris var. mongolica is divided into five forest models: tending thinning forest; grassland forest sparse; green umbrella forest; Block cutting is clear; mother forest and seed garden. There are five methods for renewal and transformation: Zhangwu County Xiaodian Yang Timber Forest; camphor, oil, red, Bansong, Pinus sylvestris var. mongolica, Pinus sylvestris var. mongolica mixed forest; Wumang maple, Cone, Xinjiang poplar, Caragana landscape forest; forest, Huzhizi, Huaihuai and other mixed forests; coniferous and broad-leaved oak irregular mixed forest, such as camphor, oil, red Spruce, sugar maple and oak. The corresponding methods for updating and renovating technical measures are proposed. The regeneration and transformation of Pinus sylvestris var. mongolica plantation in Zhanggutai sandy land should be based on the natural vegetation restoration system, with the enclosure structure as the main factor, transformed into stable coniferous broadleaf, shrub, unequal age, multi-layer mixed Lin and other models or integration. The practice over the years has shown that the shrub-grass mixed forest dominated by Mongolian pine forest should be built on the land of the loose forest of degraded disease in the Mongolian pine forest. Abstract In the healthy plantation, the broad-leaved economic tree species should be increased, and the ecological and economic mixed forest should be built to improve The comprehensive productivity of the mixed forest of Pinus sylvestris var.
