Embodiment Construction

[0087] Below in conjunction with specific embodiment and accompanying drawing, structure and working principle of the present invention are further explained:

[0088] When conducting soil erosion surveys, a basic survey unit is first selected, and plots are divided in the basic survey unit, and the continuous spatial range with the same land use type, soil and water conservation measure type, and canopy closure / coverage is divided into a plot. The plots in the present invention refer to the plots divided in the basic survey unit.

[0089] The rainfall area in the present invention refers to the continuous area with the same rainfall announced by the Meteorological Bureau. Generally, the area of ​​the plot is smaller than the size of the rainfall area.

[0090] Such as figure 1 and figure 2 As shown, the present invention provides a portable soil and water conservation benefit evaluation device, which includes a housing 1, a control unit 2 disposed inside the housing 1, an...

Abstract

The invention provides a portable water and soil conservation benefit evaluation device based on a water and soil loss calculation equation. The device comprises a shell, a control unit in the shell and a remote data server, wherein the control unit uploads obtained data to the remote data server through a wireless network and comprises a data processing unit, a storage unit with a database, a wireless communication unit and a GPS navigation unit, wherein the storage unit, the wireless communication unit and the GPS navigation unit are respectively in communication connection with the data processing unit. According to the invention, the water and soil loss calculation equation is combined with the water and soil conservation benefit evaluation, the water and soil loss evaluation value of a piece of land is obtained by calculating the water and soil loss quantity of the land under different water and soil conservation measures, and the water and soil loss situation can be quantitatively evaluated in a scientific and normative manner; moreover, the water and soil conservation measures for the land can be evaluated under three conditions.

Description

technical field [0001] The invention relates to the field of evaluation and monitoring of water and soil loss, in particular to a portable soil and water conservation benefit evaluation device and evaluation method. Background technique [0002] Soil and water conservation is a basic national policy of our country, which is related to national food security and sustainable economic and social development. Since the reform and opening up, my country has long adhered to the policy of "taking small watersheds as units, comprehensive planning, and comprehensive management" to deploy soil and water conservation measures, and has made great achievements in soil and water conservation. [0003] The concept of soil and water conservation measures is a general term for technical measures and management measures such as engineering, planting and farming to prevent and control soil erosion, protect, improve and rationally utilize water and soil resources, and improve the ecological env...
