勘查区交通以公路为主，S66和汾高速及S319省道从区块内部南侧穿 5 过，S318 省道从区块内中北部穿过，G55、太（原）-焦（作）铁路从区块 西侧外围通过，村镇间有乡道、县道连接。交通条件相对便利（图 1-1、1-2、 1-3）。 图 1-1G309 国道与 G22 长临高速 图 1-2左权西区块交通位置图 3、自然地理 1地形地貌 本区块地处太行山西麓，属于剥蚀侵蚀中山区，地形较复杂，沟谷纵 横，切割较强烈，海拔高程 1090～1520m；最大相对高差 430m。本区块内 基岩大面积出露，地势西高东低、北高南低，属中高山区，为黄土、基岩 6 剥蚀型山岳地貌（图 1-3）。 图 1-3左权西勘查区地形地貌图 2河流水系 本区属海河流域漳卫河水系。东部为清漳西源，源于和顺县八赋岭官 上一带，由川口乡蒿沟村北入境，由北向南流经区块，在区外粟城乡上交 漳村与东清漳河会合。西部为浊漳北源，其一级支流泉水河自区块内北寨 乡由东北向西南流过，于城关镇南河底村西南汇入浊漳北源（图 1-4）。 图 1-4左权西勘查区地表水系及所属流域分布图 7 3气候 本区属东亚暖温带大陆性半干旱季风气候，四季分明，冬季寒冷少雪，春季 干旱多风，夏季炎热多雨，秋季温凉湿润，光照充足，雨水偏少。年平均气温最 小 8.3℃， 最大 10℃， 一月平均温度为-6.4℃～6.8℃， 七月均温为 22.8℃～23.3℃。 年平均降雨量 501.41mm，多集中于 7、8、9 月份，占全年的 60～75；日最 大降雨量为 121mm（1998 年），连续一次最大降雨量 113.4mm（1998 年），年 平均蒸发量 1174.2mm；无霜期为 150-166 天左右。霜冻期为十月上旬至次年四 月中下旬。最大冻土深 0.6m；年平均风速 1.63m/s,最大风速 17.35m/s。 4地震 据中国地震动参数区划图（GB18306-2015）、1400 中国地震烈度区划 图及山西省地震局提供的资料，区块基本烈度为Ⅶ度，设计基本地震加速度值为 0.10g。反映谱特征周期 0.35s，属相对稳定区。 4、经济状况 本区主要农作物有玉米、谷子、高粱、小麦等，经济作物有油料、蓖麻、蔬 菜、党参、芝麻、花生等。果类有苹果、梨、杏、枣、葡萄、桃、核桃等。左权 素有核桃之乡的美誉，核桃种植已有 1000 多年的历史。左权县水资源丰富，全
