上限效果测度在林种布局树种选择中的应用

Application of Upper- limit Effect Measurment in Distribution of Forest Species and Selection of Tree Species

气象区划将松山区划分为西部、中部、东部3个气候区,全区由西向东,海拔、降水、热量逐渐减少,林木生长、分布呈现出差异。本文应用上限效果测度,依林木产量、产值、价值,布局了林种,选择了树种,为林业更大发展提供了依据。

Abstract ：Songshan District is divided into western climate area, middle climate area and eastern climate area. The altitude, precipitation and heat gradually decrease from west to east, and there are differences between the growth and distribution. The upper- limit effect measurement has been applied in distribution of forest species and selec- tion of tree species according to the yields, output values and values of forest stands, which can provide basis for the further development of forestry.
