以树种生长量信息和气候要素信息作为因变量;用大比例尺地形图、以对应于因变量的测绘信息作为自变量组成样本,建成具有定位功能的数量化混合模型(以下简称“定位化模型”)。求解后,利用地形图的公里网,按纵、横座标,以一定的水平距离进行机械布点,并查取这些点的测绘信息,用作自变量,代入回归方程,按确定的地点获得期望值,构成覆盖全研究区的空间分布信息网。
Taking tree species growth amount information and climatic factor information as dependent variables, a large scale topographic map and corresponding mapping information of dependent variable are taken as independent variables to construct a quantitative hybrid model with positioning function (hereinafter referred to as “localization model” ). After solving, using the kilometers of topographic map, according to vertical and horizontal coordinates, to a certain horizontal distance of mechanical distribution, and access to these points of mapping information, used as an independent variable, into the regression equation, according to the location of the desired value, Form a spatial distribution information network covering the entire study area.
