二十多年来在水文地质勘察生产实践中,影响半径这个参数给我们的印象,它既是地下水资源评价中一个重要参数,也是一个用旧的传统学说说不太清、求不太准的参数。鉴于在多数水文地质勘察,尤其是在松散地层的水文地质勘察评价中经常要用它,因此,对它的认识和测定,若长期地停留在旧的传统的似是而非的状态中,无疑将影响我们水文地质勘察工作的质量和水平的提高。读了《试论》和《再论影响半径》等文后,深感获益不浅,多年来我们单位在实际工作中也经常为对影响半径这个参数理解不透,求之不准,而感到有深入研究的必要。《试论》和《再论》等文解答了我们多年来一些没 For more than two decades, in the practice of hydrogeological investigation and production, the influence of radius on this parameter gives us the impression that it is not only an important parameter in the evaluation of groundwater resources, but also a parameter that is not too clear and not satisfactory for the old traditional theory . In view of the fact that it is often used in most hydrogeological surveys, especially in the hydrogeological investigation and evaluation of loose formations, its cognition and determination over the long run will undoubtedly affect us Improve the quality and level of hydrogeological survey work. After reading the essay “Trial” and “Re-discussing the Impact Radius,” I am deeply indebted to them. Over the years, our unit often understands and inaccurately affects the parameter of radius of influence in actual work Feel the need for in-depth research. Texts such as “trial” and “re-discussion” answered some of us over the years
