一、山东山区自然地理特征山东地处黄河下游,位于北纬34°20′—38°30′,东经114°45′—122°45′之间,山地丘陵面积55900平方公里,占全省土地总面积的35％。按地质构造与岩石组成,分为砂石区(岩浆岩)与青石山区(沉积岩)两大类,砂石山区占山丘总面积的73％,青石山区约占山丘总面积的27％。山东山区主要集中鲁中南与胶东半岛。鲁中南山区包括泰山、沂山、蒙山、鲁山、徂徕山等,山势陡峻,地形复杂,主峰玉皇顶海拔1545米,为全省最高峰,沂山、蒙山、鲁山、徂徕山等海拔也在1000米以上,其他低山丘陵海拔约在500米以下。
I. Natural Geographical Features of Mountainous Regions in Shandong Shandong is located in the lower reaches of the Yellow River at a latitude of 34 ° 20’-38 ° 30’N and longitude 114 ° 45’-122 ° 45’E with a hilly area of 55,900 km 2, 35% of the area. According to geological structure and rock composition, it is divided into two major categories: gravel area (magmatic rock) and Qingshi Mountain area (sedimentary rock). Gravel area occupies 73% of the total area of the hill and Qingshi area occupies 27% of the total area of the hill. Shandong mountainous areas mainly focus on Central South Shandong and Jiaodong Peninsula. Luzhongnan mountains include Mount Tai, Yishan, Mengshan, Lushan, Dalaishan, steep mountains, complex terrain, the main peak Yuhuangding elevation of 1545 meters, the highest peak in the province, Yishan, Mengshan, Lushan, Dalai Shan and other altitudes above 1,000 meters, the other low hills about 500 meters below sea level.
