Description

Technical Field

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

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

[0003] While some methods are currently available for ecological monitoring, they still face some shortcomings in monitoring the ecological and environmental impacts of shelterbelts. Traditional monitoring methods can be simplistic, often focusing on a single aspect of data, such as wind speed or soil moisture content. This makes it difficult to comprehensively and systematically assess the comprehensive ecological impacts of shelterbelts. Furthermore, existing monitoring methods may lack standardized data processing and analysis methods, which affects the accuracy and comparability of monitoring results.

[0004] Furthermore, more scientific and rational standards are needed to determine the ecological effects of shelterbelts. Relying solely on subjective judgments or simple comparisons of indicators will not accurately reflect the actual ecological effects of shelterbelts under different environmental conditions.

[0005] Therefore, in order to better protect and manage shelterbelt resources and improve the ecological benefits of shelterbelts, there is an urgent need for a comprehensive, accurate and scientific method for monitoring the ecological and environmental effects of shelterbelts.

The method for monitoring the ecological environment effect of a shelterbelt according to claim 2, characterized in that: The climate coefficient formula is: Z3=α4×(PT2×BT2-PT2×BT1)+α5×(PD2×BD2-PD1×BD1) In the formula, α4 and α5 are the corresponding preset weight values; Z3 is the climate coefficient of the shelterbelt during the specified period; PT1 and BT1 are the average and changing rates of temperature values ​​in the inner area of ​​the shelterbelt, respectively; PT2 and BT2 are the average and changing rates of temperature values ​​in the area surrounding the shelterbelt, respectively; PD1 and BD1 are the average and changing rates of humidity values ​​in the inner area of ​​the shelterbelt, respectively; PD2 and BD2 are the average value and change rate of humidity in the area surrounding the shelterbelt, respectively.

7. The method for monitoring the ecological environment effect of a shelterbelt according to claim 2, characterized in that: The comparison method in Step 1.6 is as follows: Where X1 < X2, If X≤X1, the ecological effect of the shelterbelt is judged to be poor, and the first display signal is generated; If X1<X≤X2, the ecological effect of the shelterbelt is judged to be average, and a second display signal is generated; If X>X2, it is determined that the ecological effect of the protective forest is good, and a third display signal is generated.

8. The method for monitoring the ecological environment effect of a shelterbelt according to claim 2, characterized in that: To determine whether the ecological effect of the shelterbelt is good, the windbreak and sand fixation coefficient of the shelterbelt within a specified period is compared with the preset windbreak and sand fixation threshold; When the wind and sand fixation coefficient exceeds the preset wind and sand fixation threshold, it means that the wind and sand fixation performance of the shelterbelt has improved; when the wind and sand fixation coefficient does not exceed the preset wind and sand fixation threshold, it means that the wind and sand fixation performance of the shelterbelt has decreased.

9. The method for monitoring the ecological environment effect of a shelterbelt according to claim 2, characterized in that: To determine whether the ecological effect of the shelterbelt is good, the soil and water conservation coefficient of the shelterbelt within a specified period is compared with the preset soil and water conservation threshold; When the soil and water conservation coefficient exceeds the preset soil and water conservation threshold, it means that the soil and water conservation performance of the shelterbelt has improved; when the soil and water conservation coefficient does not exceed the preset soil and water conservation threshold, it means that the soil and water conservation performance of the shelterbelt has decreased.
