Abstract

With the rapid economic and social development, human disturbances to the ecosystem have become more and more intense. However, the scale of regional economic and social development, supported by regional water resources, has boundaries. The central government and local governments of all levels have clearly proposed to carry out water resources carrying capacity evaluation and early warning. From the perspective of the actual management of the county water administrative department, with the administrative divisions within the county as the basic unit, the principle of index selection and index grading standards determination is proposed, and an index system including the four major levels of society, economy, water resources, and ecology is constructed. Then, combined with the functions of various government departments, the basic framework of a universal water resources carrying capacity early warning mechanism, including three major processes: carrying capacity evaluation and update, early warning information release, and implementation of differentiated control measures, is proposed.

Highlights

For human survival and development, water resources, one of the most important material resources, are indispensable, and is the basic support for economic development and related to economic security, ecological security and national security
The central government and local governments of all levels clearly stated in the water-saving action plan that water resources carrying capacity evaluation, monitoring and early warning should be carried out
From the perspective of the management practice of the county water administrative department, this research focuses on the actual water resources management of the county, and proposes to construct the evaluation index system and evaluation method of the regional water resources carrying capacity with the administrative divisions within the county as the basic unit

Summary

Introduction

For human survival and development, water resources, one of the most important material resources, are indispensable, and is the basic support for economic development and related to economic security, ecological security and national security. General Secretary Xi Jinping pointed out that water has become a severely short product in China, and proposed that the county should be used as a unit to evaluate the carrying capacity of resources and the environment and establish an early warning mechanism. Resources carrying capacity research should be basic models, internal mechanisms, water control results, calculations model, system platform, dynamic evaluation, early warning and control, and etc. From the perspective of the management practice of the county water administrative department, this research focuses on the actual water resources management of the county, and proposes to construct the evaluation index system and evaluation method of the regional water resources carrying capacity with the administrative divisions within the county as the basic unit. On the basis of considering the actual use of water resources in the county, the grading standards of these indicators should be determined based on the spatial differences between regions
