Description

Technical Field

[0001] The invention relates to the technical field of ecological environment monitoring, and in particular to a method for monitoring the ecological environment effect of a protective forest. Background Art

[0002] As global environmental issues become increasingly prominent, ecological environmental protection has become a focus of attention. As an important ecological engineering measure, shelterbelts play a key role in preventing wind and sand, conserving water and soil, and regulating climate. However, to ensure that shelterbelts continue to effectively perform these ecological functions, it is necessary to conduct scientific and accurate monitoring of their ecological and environmental effects.

[0003] At present, although there are some methods for monitoring the ecological environment, there are still some shortcomings in monitoring the ecological and environmental effects of shelterbelts. Traditional monitoring methods may be relatively simple and often focus on only one aspect of data, such as monitoring only wind speed or soil moisture content, which makes it difficult to comprehensively and systematically evaluate the comprehensive ecological effects of shelterbelts. At the same time, existing monitoring methods may lack standardized data processing and analysis methods, which affects the accuracy and comparability of monitoring results.

[0004] In addition, the determination of the ecological effects of shelterbelts also requires more scientific and reasonable standards. It is difficult to accurately reflect the actual ecological effects of shelterbelts under different environmental conditions by relying solely on subjective judgment or simple indicator comparison.

[0005] Therefore, in order to better protect and manage shelterbelt resources and improve the ecological benefits of shelterbelts, a comprehensive, accurate and scientific method for monitoring the ecological and environmental effects of shelterbelts is urgently needed. Summary of the invention
