水庫范圍

壩址位于江西(xi)省(sheng)萬安縣(xian)城芙蓉鎮上游2千(qian)(qian)米處土橋頭，地處東經114°41′，北(bei)緯26°33′，上游距贛州(zhou)市、下游距吉安市各90千(qian)(qian)米，控制流域面積36900平方千(qian)(qian)米。水庫回水長度(du)90千(qian)(qian)米，回水涉(she)及吉安市萬安縣(xian)、贛州(zhou)市贛縣(xian)區(qu)和章貢區(qu)。

自然環境

地質地貌

水庫坐落在低山(shan)(shan)(shan)丘陵地帶，庫周低山(shan)(shan)(shan)丘陵連(lian)綿起(qi)伏，壩址地處低山(shan)(shan)(shan)丘陵邊緣，河谷寬(kuan)闊，復式河槽左(zuo)半部(bu)(bu)為河床段(duan)，寬(kuan)450米(mi)(mi)，右半部(bu)(bu)由漫(man)灘和Ⅰ、Ⅱ級(ji)階地組成，寬(kuan)500米(mi)(mi)，覆(fu)蓋(gai)層厚13米(mi)(mi)，左(zuo)側(ce)山(shan)(shan)(shan)坡35°～50°，右側(ce)山(shan)(shan)(shan)坡25°。地處華南地層區(qu)，構造單(dan)元為贛(gan)中(zhong)南褶隆，贛(gan)州(zhou)—吉安(an)拗陷，大湖山(shan)(shan)(shan)—芙蓉山(shan)(shan)(shan)隆斷束。地質年代屬中(zhong)生代侏羅紀，新生代第四(si)紀。巖層分中(zhong)上統羅凹群(qun)，巖性為淺(qian)變質白色石英砂巖、粉砂巖和砂質頁(ye)巖，斷層發育，較大斷層7條，斷距0.2米(mi)(mi)～8米(mi)(mi)。地震烈度小于(yu)Ⅵ度。

主要支流

庫(ku)區水(shui)系(xi)發達，贛江在庫(ku)尾贛州市八境臺于左岸納章(zhang)水(shui)后入(ru)庫(ku)，另有6條(tiao)流(liu)域(yu)面(mian)積大于100平(ping)方千米的支流(liu)入(ru)庫(ku)：左側長村河(he)、攸(you)鎮河(he)、皂口(kou)水(shui)，右側湖江河(he)、良口(kou)水(shui)、武術水(shui)。

氣候水文

庫區屬(shu)中亞熱帶季風濕潤(run)氣(qi)候區，多年平均(jun)氣(qi)溫(wen)18.5攝氏度、年降水量(liang)1560毫米（4～9月(yue)占68.7%）、年水面蒸發量(liang)893毫米。

水土流失治理

庫區森林曾(ceng)遭受1958年大(da)煉鋼鐵、“文革”、1980年分山到(dao)戶3次較(jiao)大(da)范圍砍伐。20世紀90年代起，采取(qu)封山育(yu)林、栽(zai)種經濟果(guo)林等措施(shi)加強治理，水(shui)(shui)土(tu)流失得到(dao)有效遏制，植被覆(fu)蓋率88%。庫水(shui)(shui)清澈，2006年12月(yue)，水(shui)(shui)質達Ⅱ類地表水(shui)(shui)標準，已劃定(ding)水(shui)(shui)功(gong)能保留區2個(ge)，飲用水(shui)(shui)源區1個(ge)。
