小兴安岭 位于中国黑龙江省东北部。西北接伊勒呼里山,东南到松花江畔,长约500千米。西北-东南走向。山势低缓,海拔600~1000米。主峰平顶山,海拔1429米。分水岭两侧不对称,西南坡缓长,东北坡陡短。东南段主要出露花岗岩和变质岩,为长期隆起剥蚀区。西北段广泛分布第三纪陆相沉积。第三纪末、第四纪初才沿东北、西北向断裂抬升,并与东南部连接。与此同时,伴随有玄武岩喷发。小兴安岭东北侧的逊河流域保存有大片玄武岩台地,东南侧德都附近有五大连池火山群,直到1719、1921年还有火山喷发。是中国主要林区之一。西北部以兴安落叶松、白桦为主,东南部则以红松、鱼鳞松、臭松、水曲柳、椴树等为主。有铁路通往伊春市乌伊岭。 |
