Description

Technical Field

[0002] The loess hilly gully area is the main area for the implementation of soil and water conservation projects. The soil and water conservation projects in this area are of various types and implemented over a wide area. However, the soil and water conservation forestry and grassland projects in this area are mainly operated in a natural state, lacking efficient development experience activities. At present, the evaluation of soil and water conservation forestry and grassland projects is mainly based on benefit evaluation, mainly on soil and water conservation, water conservation and wind and sand fixation function evaluation, and the previous evaluation can only evaluate a single function.

[0003] The relevant benefit evaluation methods are no longer adapted to the actual needs of multiple functions and uses. For example, if only ecological benefits are emphasized, even if the ecological benefits are good, economic benefits cannot be provided, which will also reduce the enthusiasm of people in the project area to participate in soil and water conservation. For another example, local economic development is mainly based on animal husbandry, and the soil and water conservation forest and grass projects require large-scale closure and cultivation, which conflicts with animal husbandry production and the interests of farmers and herdsmen, leading to resistance from farmers and herdsmen, and the project cannot be effectively implemented.
