| 摘 要： | 为了揭示祁连山北坡青海云杉的结构规律,探索该树种各测树因子之间内涵相关关系,对祁连山8个林场设置6株树样园295个,实测样木1695株,建立年龄,胸径、树高与各测树因子的数学模型11个,对科学经营祁连山水源林提供了一定依据,其目的是使祁连山水源林的经营管理逐渐走向科学化,不断提高和扩大森林的质量和数量,使其发挥愈来愈大的水源涵养效益。

The Prelimnarv study on the Mathematics Models of Tree Measurement Factors of Picea Crassifolia on the Nerthern Slope of Mountain Qilianshan |

| Abstract: | In order to show the laws governing the structure of Picea Crassifolia on the Northern slope of Mountain Qilianshan, and to examine the interrelated relation belmeen factors of tree measurement, samlple 295 rounds made up of six trces have been set up on eight forestry centres in Mountain Qilianshan and 1695 sample trees have been surveyed, Eleven mathematics models have been built for age, diameter, height and factors of tree measurement. All this provide some basis for scientific management of water reservoir fosest in Qilianshan. The purpose is to manage of water reservoir forests in Qilianshan more scientifically and to raise and enlarge the quality and quantity of the forest continuesly so as to bring its water reservoir conservatiew benefits into full play. |
