温带针阔混交林区树种胸径生长的空间差异性

利用方差分析理论研究了样地各树种在各径阶生长量的空间差异性,结果表明：在温带针阔混交林区中红松、云杉、冷杉、水曲柳、胡桃楸、黄菠萝等树种在各径阶的生长量受海拔、坡向和坡度不同的影响较大,而落叶松、柞树和杨树等树种在各径阶的生长量受地理位置的影响较小,坡位因素对于各树种的生长影响均较小.

Spatial Difference of the DBH Growth of Species in Temperate Broadleaved-Coniferous Mixed Forest

Spatial difference of the DBH growth of species is studied by Variance Analysis theory in various size. It shows that there is significant difference for the DBH growth of Korean pine, Chinese Spruce, Fir, Manchurian Ash, Manchurian walnut, Amur Cork -tree in various size about altitude, slope direction and slope in temperate broadleaved - coniferous mixed forest, and the DBH growth of Larix, Manchurian oak and poplar tree in various size is less affected for the geographical position, the growth of tree species is less affected for slope position.
