东岔林区水资源调查及河岸线保护措施

Investigation of Water Resources and Protection Measures of Riverbank in Dongcha Forest Region

摘要: 河湖岸线既具有行洪、调节水流和维护河湖健康的自然与生态环境功能，同时又在一定情况下具有开发利用价值。本文针对东岔林区东岔河展开水资源调查，从东岔河基本情况、年平均流量、涉河工程、水功能区区划等方面阐述并进行分析，结果显示：东岔河岸线生态环境和水质优良；年平均年径流总量为4353万m3，属中小型河流；涉河工程与水功能区区划不明确，河势纵向、横向稳定系数分别为0.22~1.16、0.55~0.77，稳定性较差；依据现状区划分为3个类型8个功能区；提出了6项保障措施及建议。对实现河岸线资源的科学管理、合理利用与有效保护，对维护东岔河健康发展，保护生态环境，推进水生态文明建设，促进经济社会可持续发展具有重要意义。

Abstract: The river and Lake shoreline not only has the function of flood, regulating water flow and main-taining the health of the river and lake, but also has the value of development and utilization under certain conditions. Based on the water resources investigation of Dongcha River in Dongcha forest area, this paper expounds and analyzes the basic situation, annual average discharge, river-crossing project and water function zoning of Dongcha River, the results show that the ecological environment and water quality of Dongcha River are excellent, the annual average annual runoff is 43.53 million m3, and it is a small river, the longitudinal and lateral stability coefficients of river regime were 0.22~1.16 and 0.55~0.77, respectively, which had poor stability. According to the current situation, it is divided into 3 types and 8 functional areas, and 6 safeguard measures and suggestions are put forward. it is of great significance to realize the scientific management, rational utilization and effective protection of riparian resources, to maintain, Dongcha river, to be healthy, to develop, to protect the ecological environment, to promote the construction of water ecological civilization, and to promote the sustainable development of economy and society.
