Problems solved by technology

However, the factors for quantifying the carrying status of regional water resources and environment and determining the level of early warning and warning are extremely complicated
At present, a large number of experts and scholars at home and abroad have conducted research on water resource issues from the perspectives of water resource monitoring, allocation management, development and utilization, and have achieved many research results. The early warning of regional water resource environmental bearing status is a relatively new direction. Most of the existing early warning methods do not consider the impact of the change trend of the carrying state on the early warning results, and cannot reflect the connotation of the carrying state of the water resources environment

Embodiment 1

[0056] In step 1, it is assumed that there are 6 sub-regions, which are partitions 1-6 respectively. A total of 9 indicators were determined, which are water resources per unit area, water quality compliance rate of water function areas, GDP per capita, population density, water consumption per 10,000 yuan of GDP, COD per 10,000 yuan of GDP, ammonia nitrogen per 10,000 yuan of GDP, water surface rate, and urban greening rate. The index values ​​of each partition in this embodiment are shown in Table 1.

Abstract

The invention discloses a regional water resource environment bearing state early warning method, which comprises the following steps of: firstly, taking a coordinated development degree between a water resource bearing subject and a bearing object as an early warning index for quantitatively reflecting a regional water resource environment bearing state, and selecting 9 indexes for reflecting thebearing subject and the bearing object to construct a comprehensive early warning index system; Determining the weight occupied by each index by using an entropy weight method; Quantitatively calculating the bearing state of the regional water resource environment by using the concept of the coordinated development degree, and dividing the bearing state level; Based on the regional water resources environmental bearing status division results and the regional water resources, social economic, ecological environment system evolution trend, formulating the regional water resources environmentalcarrying status warning standard, and then alerting the regional water resources environmental carrying status According to the method, the early warning annual bearing state and the change trend ofthe early warning annual bearing state and the reference annual bearing state are considered, and subjectivity of an early warning result is avoided; And a basis is provided for determining the direction of lifting the bearing state and making an improvement measure.

Description

technical field [0001] The present invention relates to water resources evaluation and management methods, in particular to a method for early warning of regional water resources environment bearing status. Background technique [0002] The carrying status of regional water resources and environment is the state of interaction and influence between the main body (water resources system) and the carrying object (social economy, ecological environment system) of the region. Early warning of the carrying status of water resources and environment is the water management department's response to possible emergencies. Adverse situations are prepared in advance and the basis and basis for proposing control measures. However, the factors for quantifying the carrying status of regional water resources and environment and determining the level of early warning and warning are extremely complicated. At present, a large number of experts and scholars at home and abroad have conducted r...
