摘要: 本文运用模糊聚类分析方法, 将樟子松的适宜气候生态区划分为如下3个类型: Ⅰ、容易引种的气候生态区, 属森林草原区; Ⅱ、适宜引种的气候生态区, 主要在半干旱的草原区; Ⅲ、难于引种的气候生态区, 主要指半荒漠和荒漠区。这三种类型基本上反映了目前樟子松引种的实际情况。

Abstract: In this essay,by using fuzzy Cluster analysis method,climatic ecotopes(CE)in North China where Mongolian Scotch pine(MSP)(Pinus sylvestris var. mongolica Litv.) have been introduced were divided into three types: 1) CE for MSP-introduction easily(yn, forest-grassland belt); 2) CE for MSP-introduction suitably(in grassland belt) ; 3)CE for MST-introduction difficultly(in semidesert and desert belt). MSP intreduction on the sandy lands in semidesert and desert whert precipitation is lessthan 250mm(sometimes 300mm) is almost unsuccessful without irrigation.
