Hydrological data, as an indispensable part of hydrological work, provides an important basis for the development and utilization of water resources and the construction of water conservancy projects, and can meet the actual needs of different departments for hydrological data. Therefore, by improving the quality of hydrological data, we can better ensure the important role of hydrological data and make it play an important role in promoting social and economic development.

1 Factors affecting the quality of hydrological data

Error of original hydrological data 1. 1

1. 1. 1 Influence of water resources development and utilization on hydrological data quality

China's agriculture and industry, as the basic industries of the national economy, are of great significance to China's economic construction. With the continuous acceleration of industrial and agricultural development, the development and utilization of water resources are also increasing, and the pollution caused by water resources is also increasing, which puts forward higher requirements for the workload of water resources data collation. In addition, in the process of water resources development and utilization, there are more and more uncertain factors in hydrological data collection, which have a great impact on the quality of hydrological data.

1. 1.2 Impact of urbanization on hydrological data quality

Under the new situation of accelerating urbanization in China, the land use pattern in China has changed greatly, which also has a great impact on the collection of hydrological data.

1. 1.3 Influence of water conservancy project construction on hydrological data quality

Strengthening the construction of water conservancy projects can effectively realize the rational allocation of water resources and better promote the development and utilization of water resources. However, in the current construction of most water conservancy projects in China, the hydrological characteristics are directly affected, which will inevitably affect the accuracy of hydrological data compilation.

1.2 hydrological data compilation technology

In hydrological work, hydrological reorganization is usually used to collect original hydrological data in order to better realize the value of hydrological data itself. This also makes hydrological reorganization technology directly affect the quality of hydrological data. When hydrological reorganization technology has strong standardization, it will also effectively ensure the scientificity of hydrological data reorganization methods and improve the quality of hydrological data, otherwise it will adversely affect the quality of hydrological data.

1.3 Hydrological data recombiner

The quality of hydrological data reorganization is closely related to the quality of the reorganizers, who are the main body of reorganization, and their working ability and professional ethics directly affect the quality of hydrological data. Therefore, in order to effectively improve the quality of hydrological data, it is necessary to do a good job in training the reorganization personnel to ensure the improvement of their comprehensive quality.

2 Countermeasures to improve the quality of hydrological data

2. 1 Promote the healthy development of the hydrological industry

The accuracy and quality of hydrological data will directly affect the development and utilization of water resources and the construction of water conservancy projects. Therefore, in hydrological work, it is necessary to continuously improve hydrological detection and reorganization technology, and hydrological practitioners also need to strive to improve their professional knowledge, master various new technologies and methods, and ensure the improvement of their professional quality, so as to better serve hydrological work, ensure the improvement of hydrological data quality, and make hydrological data play an important role in economic construction.

2.2 Strictly control the reorganization of hydrological data.

2.2. 1 Reasonable review of hydrological data

The first is to strengthen the audit of the accuracy of hydrological tests. The accuracy of hydrological data inspection is one of the key factors affecting the quality of hydrological data. In addition to grasping the accuracy in the test, we should also strengthen the audit of the test accuracy in the data sorting work, and examine whether the test technology conforms to the actual situation, whether the test scheme and skills conform to the actual situation, how big the error of the test results is, whether it has been made up, and whether there are remedial measures. Second, the internal quality of hydrological data, including whether it is true and complete, should be audited. False information found in the audit should be eliminated, and problems should be rectified in time.

2.2.2 Pay attention to improving the correctness and rationality of the review.

First, it is necessary to strengthen the audit of original data and consolidate the quality foundation of hydrological data. In the process of collecting the original data, it will inevitably be influenced and interfered by many factors, which will lead to certain errors in the collected data. Therefore, when compiling data, we should strengthen the audit of the original data to ensure the authenticity, accuracy and integrity of the data. The second is to increase the review of the reorganization results. Compare, analyze and check related items and data, such as daily rainfall and annual rainfall, daily water level and hourly water level data, so as to minimize the degree of data error and avoid large data error.

2.2.3 Effectively strengthen data reorganization.

In order to improve the quality of hydrological data, it is necessary to strengthen the data collation, which can effectively improve the close relationship between testing and collation, and in the process of data collation, it is necessary to feedback the problems found in the test in time to further improve the testing work. Moreover, the data can be reorganized and strengthened, which is beneficial for testers to fully consider the reorganization requirements in the testing work and ensure that the systems of forecasting and sending reports can be effectively implemented and executed.

2.3 improve the comprehensive quality of hydrological staff

People play a leading role in the compilation of hydrological data. Only through the joint efforts of all staff can high-quality hydrological data be compiled. It can be said that the comprehensive quality of hydrological staff will directly affect the quality of hydrological data, and efforts should be made to improve the comprehensive quality of hydrological staff to ensure the overall quality of hydrological data. Therefore, it is necessary to strengthen the training of hydrological staff's professional ability, so that they can master the contents of hydrological mapping and take it as an important guide in their work. Hydrological work has a strong practicality. When hydrological characteristics change, it will have a great impact on the compilation of hydrological data. Therefore, hydrological staff need to strengthen the accumulation of experience in practical work to ensure the improvement of hydrological data quality.

2.4 Strengthen the accuracy of hydrological tests

Hydrological monitoring, as a very important link in the compilation of hydrological data, has strong practical characteristics, and it is necessary to choose appropriate testing techniques and methods according to the actual situation of hydrological testing in the specific implementation process. In hydrological test, there is great flexibility in the formulation of test scheme and the selection of test skills, but it needs to meet the requirements of hydrological test accuracy, and the existing errors need to be found in time in the specific test process, and corrected and made up in time.

label

Hydrological data is a very important content in hydrological work, and improving the quality of hydrological data can not be completed overnight. It is a systematic project and needs a long process. We need to correctly understand the influencing factors of hydrological data quality in practical work and formulate targeted measures, so as to effectively improve the quality of hydrological data, accelerate the development and utilization of water resources and the construction of water conservancy projects, and play an active role in promoting China's social and economic development.
