燕山燕山Yan ShanYQn ShQn燕山(Yan shan)中国华北地区重要山脉，战略要地。西起洋河，东至山海关，北接坝上高原，西南以桑干河与太行山相隔。东西长约420千米，南北最宽处近200千米，海拔600一1 500米，主!]摩雾灵LIJ，海拔2 116米。燕山山月永，山势陡峭。地势西北高，东南低。北缓南陡，沟谷狭窄，地表破碎，雨裂冲沟众多。以潮河为界分为东、西两段。东段多低山丘陵，海拔一般1 000米以下，植被茂盛，灌木、杂草丛生，森林面积广阔。西段为中低山地，一般海拔1 000米以上，植被稀疏，间有灌丛和草地。山脉间有承德、怀柔、延庆、宣化等盆地。水系发达，河流广布，主要有洋河、潮白河和滦河等。蓄水量超过20亿立方米的大型水库有密云、官厅、潘家口3座。属温带半湿润大陆性季风气候，年平均气温5一巧℃，1月平均气温一3一12℃，7月平均气温约22℃。年平均降水量400一?00毫米。沿山脊筑有长城，形势险要。喜峰口、古北口、黄花城、居庸关、东方口、独石口、张家口是燕山长城重要关隘，自古以来是由燕山以北进人华北平原的重要孔道。今有北京一承德、北京一通辽、北京一包头铁路和公路通过。燕山山脉是华北平原北部的重要屏障，内蒙古高原和东北地区进人华北平原的必经之地。蒙古成吉思汗六至十年(1211-1215)，成吉思汗三次围攻金中都(今北京)，主力都是翻越燕山山脉，以丰利(今张北县西)、宣德(今宣化)、居庸关和古北口、擅州(今密云)、顺州(今顺义)为主要进攻路线。抗日战争时期，八路军晋察冀军区第4纵队与冀东人民一道，依靠燕山山脉的复杂地形，开展游击战争，并以雾灵山地区为中心，创建了冀东抗日根据地。(郭玉良)
