产区区划是按照树种的生物学特性、产量及地域的分异规律制订的。它不仅从客观上反映了不同地域的水、热、光照、土壤等条件对林分生产力的影响,同时也可将各区实际的和潜在的生产力加以分析比较,制定出各产区的特点及等级。产区区划是林业生产的基本建设,又是一项复杂的基础科研任务。不仅具有理论研究的重大意义,对指导营造速生丰产林也有一定的现实意义。本文是依据东北山地落叶松、红松、
Production zoning is based on the biological characteristics of species, yield and geographical differentiation of the law developed. It not only objectively reflects the impact of different regions such as water, heat, light and soil conditions on the productivity of the stand, but also analyzes and compares the actual and potential productivity of each district to formulate the characteristics and grading of each producing area . Production zoning is the basic construction of forestry production, but also a complex basic scientific research tasks. It not only has the great significance of theoretical research, but also has certain practical significance to guide the fast-growing and high-yield forest. This article is based on northeastern mountain larch, Korean pine,
