第一章 江津概况
一、地理位置
江津区地处四川盆地东南边缘，介于东经105°49′至106°36′，北纬28°28′至29°28′之间，东西宽约80公里，南北长约100公里。江津东邻巴南、綦江，南靠贵州习水，西依永川、四川合江，北接璧山及重庆九龙坡区，距重庆都市区46公里，地处重庆中心城镇群范围，境内有成渝铁路、渝黔铁路、成渝高速公路和长江水运与重庆相连。 二、行政区划
江津区域总面积3219平方公里，其中陆地面积3060.1平方公里，水域面积158.9平方公里。市域建设用地面积296.3平方公里。
目前，江津区设3个街道办事处（几江、德感和支坪街道办事处）、23个镇和四面山管委会、380个行政村。江津区人民政府驻在几江街道办事处。 三、自然条件 （一）地质地貌
1、地貌
江津地处四川盆地东南边缘，云贵高原北坡大娄山余脉梯间过渡地带，境内山丘密布，河流纵横。地貌以丘陵兼低山为主，丘陵面积2102.18平方公里，占全区总面积的65.31%；山地面积1017.63平方公里，占全区总面积的31.61%；平坝阶地99.19平方公里，占全区总面积的3.08%。全区地形南高北低，山区多在南部。区境内计有78座大小山岭，海拔最高处四面山蜈蚣坝1709.4米，最低处珞璜镇中坝178.5米，相对高差1530.9米。
2、地质
江津广泛分布侏罗、白垩系地层，以砂岩和页岩为主。由于大部分岩层近于水平，砂岩与页岩相间，经过地质运动和溪流的切割而形成一些高丘台地，如篆山坪、滚子坪、云雾坪、艾坪等，相对高差达100米左右。
沿江的山岭槽谷由中生代石灰岩、页岩及砂岩组成，当表层砂岩被剥蚀后，下部石灰岩出露并经流水侵蚀发育成二岭一槽，呈船型地貌。槽谷内有小型岩溶地形。
