    在對重慶市的自然地理情況和社會經濟情況作了介紹之後，還分析了重慶市水資源的基本特徵，目前重慶市的水資源利用還處在傳統的開發利用階段，水資源管理體制還存在許多弊端，水的法規制度建設也相對落後，水的供給還不能完全滿足需求，水質狀況沒有得到根本性的改善，水土流失還很嚴重，水旱災害發生的頻率比較高。針對重慶市水資源利用的現狀，本文提出：應加強對水資源持續利用的認識；改革目前重慶市的水管理體制，嘗試水務局管理體制，相應加強水的法規和制度建設，實現需水管理，建立節水型社會；根據實際情況，加強水利建設，實現水的供需平衡；依據「控源導流」的思想控制水污染，實現清潔生產；治理水土流失，保護水環境；建設防洪減災體系。
