雨水集蓄利用技术--水窖在秦安县的应用与发展

阐述并分析了秦安县境内水窖的基本构造、配置模式和可集水量。对工程的主体部分和集流面做了较详细的说明，主要是在防渗处理和水质保护方面；提出了可集水量及主要影响因素——集流效率的计算公式和影响参数。为了切实保障人畜饮水安全，能够更加充分有效地利用当地有限的雨水资源，文章在水质保护、水窖数量和单水窖容积以及窖水灌溉技术三个方面提出优化设计方案，希望能起到抛砖引玉的作用，为我国其他干旱地区有效利用雨水提供参考。

The Application and Development of Water Cellar--a Rainwater Catching Technology in Qin'an County

This paper elaborates and analyses the basic structure,equipment pattern and available catchments capacity of the water cellars in Qin'an County;and explains their main parts and catchments surface,emphasizes particularly on the treatment of the seepage prevention and the protection of the water quality.At the same time,the paper put forward the catchments capacity and the calculation formula and the influence factors of the catchments efficiency that affects the catchments capacity basicly,In order to protect the local human and animals watering security and utilize the limited rainwater effectively,the paper put forward the optimized schemes in the protection of the water quality,the number,the volume of the water cellars and the irrigation technique.The results may use for reference and provide a base for other semidried region to utilize the rainwater efficiently.
