DZ/T 0271-2014Code for the designing of regional groundwater level monitoring network (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard was proposed by the Ministry of Land and Resources of the People's Republic of China.

This standard is under the jurisdiction of the National Land Resources Standardization Technical Committee (SAC/TC93).

This standard was drafted. China Geological Environment Monitoring Institute, Beijing Geological Environment Monitoring Station, Shandong Provincial Geological Environment Monitoring Station, Xinjiang Uygur Autonomous Region Geological Environment Monitoring Institute.

Introduction

Groundwater monitoring and its results are to carry out hydrogeological research, master the status of groundwater resources, rational development and utilization, and management of groundwater resources.

The basis for the work of source and science to prevent and control geological disasters and effectively protect the geological environment.

China has carried out groundwater monitoring work for more than 50 years. Most of the special monitoring wells used are hydrogeological exploration and Some of the remaining water source sites are used for the use of groundwater production wells as monitoring wells, as they are not built for monitoring networks (points).

If it is set up, it cannot fully meet the requirements of groundwater dynamics in the monitoring area, and the goal of groundwater monitoring cannot be achieved.

In order to carry out overall planning for groundwater monitoring, build a high-level and high-efficiency groundwater monitoring network, and actively promote the monitoring network.

(point) construction, comprehensively improve the decision support and information service level of groundwater monitoring work, need to monitor the design of regional groundwater level monitoring network the background survey of the survey area, the investigation and evaluation of the status quo of the monitoring network, and the design of the density of the monitoring network are standardized, and the previous work experience is fully absorbed.

Based on this, this standard has been developed.

Design specification for regional groundwater level monitoring network

1 Scope

This standard specifies the regional data collection and analysis of the design of the regional groundwater level monitoring network, the investigation and evaluation of the current status of the monitoring network, and the monitoring network.

Requirements and methods, and the way in which results are produced.

This standard is applicable to the encryption and improvement of the groundwater level monitoring network in the existing area, and is also applicable to the monitoring of the groundwater level monitoring network in the blank area.
