Description
Technical field
The present invention relates to soil erosion modulus to calculate technical field, specially a kind of to be applied to the survey of small watershed erosion modulus
The apparatus and method of calculation.
Background technique
The soil erosion is both to influence the important surface process of the world's ecosystems, while also resulting in serious and extensive soil
Ground is degenerated and agricultural productive force decline, is to influence one of human survival and the global environmental problem of development.World wide at present
Inside generally carry out the project developments such as the roads such as railway, highway and city-building, mine and water power, soil strong disturbance and water
Soil keeps facility to destroy, and seriously exacerbates soil erosion.
Quantitatively assessment soil erosion amount is evaluation soil erosion degree, soil and water conservation and its effect assessment and soil
Earth corrodes monitoring, the crucial foundation of management and basis, and the most important index for measuring soil erosion and soil erosion degree is soil
Earth erosion modulus, soil erosion modulus refer to the soil erosion amount on unit time unit area, often to corrode quality (t/
(km2A)) or every year corroding soil thickness (mm/a) indicates.
For a long time, the determination method of soil erosion modulus has mensuration, stylus method, plant benchmark in soil erosion study
Method, erosion groove sample prescription measure method, reservoir sedimentation measurement method etc., but survey since different regions natural environmental condition is limited and studied
The determination of accuracy of measurement causes these methods to be difficult to meet reality research needs, and the various Model of Soil Erosion occurred in the world,
Such as AM General soil loss equation (USLE), soil erosion prediction model (WEPP), European EUROSEM, ANSWERS mould
Type, with being suitable for gentle slope, and the determination of each parameter is also complex more for these models, and is suitable for Large-scale areas or basin
Range scale.
Since development construction item carries out Soil Loss Prediction and monitoring shortage data scarcity, Project Areas soil erosion mould
Number is surveyed according to the observational data of other regional runoff plots, field investigation, river sediment transport data, hydrologic survey data mostly
It calculates.However, this method artificial subjective factor is affected, prediction result lacks persuasion.For the soil after engineering construction disturbance
The determination method of earth erosion modulus value often uses empirical estimation method, and the method is mainly foundation " classification of soil erosion grade scale ",
Make interpretation in direct scene, it is seen that this method artificial subjective factor influences result very big；In addition there are analogy methods and expert to estimate
Survey method, wherein analogy method is to be passed through using soil erosion modulus after similar area, the disturbance of similar development construction item as foundation
To two project analyses, appropriate amendment is done to relevant parameter, to predict the soil erosion modulus after disturbance, it is seen then that
The determination of the correction factor of the selection and parameter of analogy project the result of this method is influenced it is very big, and expert prediction method be according to
According to the knowledge and experience of expert, the physical geography condition according to Project Areas is made prediction, and this method artificial subjective factor influences
It is very big.It can be seen that at present for the soil erosion of the small range or region generated in development construction item and its each project implementing process
Amount lacks economic, quick quantitative evaluating method and technology.
