Foreword

This standard replaces GB/T 15774-1995 "Soil and Water Conservation Benefit Calculation Method." This standard compared with GB/T 15774-1995, modified as follows. a) Classification benefit calculation, the base efficiency to water diversion and soil conservation benefits, and Table 1, relevant content to do the necessary changes. b) water diversion and soil conservation benefits calculated to increase the content of slope and watershed drainage runoff regulation capacity, efficiency and diversion words FIG. c) economic calculation, calculation of indirect economic benefits to simplify the content resources of land value-added benefits expressed in words, and water conservation work Cheng cited benefit calculation of water content. d) eco-efficiency calculations, simplified hydrosphere, soil ring, gas and biosphere in part, to increase carbon sequestration benefits; increased quality stand The amount of forest canopy density and grass coverage and other content; the plants and grass coverage to coverage. e) social computing, intercepting sediment review of the calculation formula; increase the relevant provisions of the non-point source pollution. The Standard Appendix A, Appendix B, Appendix C, Appendix D and Appendix E are informative appendices. This standard was proposed by the Ministry of Water Resources.

Introduction

GB/T 15774-1995 has implemented more than ten years in soil and water conservation benefit calculation has played an important role in guiding. With the change of social and economic development of rural industrial structure and content of soil and water conservation, nature, it is also undergone a profound change Of. In order to adapt to the soil and water conservation work under the new situation, to further standardize the calculation method of soil and water conservation benefits, according to Department of International In cooperation with the Science and Technology Division, Division of Soil and Water Conservation unified arrangement of GB/T 15774-1995 been revised. Soil and Water Conservation Benefit Calculation Methods

1 Scope

This standard specifies the principles, contents and methods of soil and water conservation benefit calculation. This standard applies to water and wind erosion and water erosion interleaving region Small Watershed Comprehensive Management Benefit calculation can also be used for large Benefit Basin and in different areas of administrative units (province, district, county, township and village) Calculation of Soil and Water Conservation.

2 Normative references

The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 15773-2008 acceptance of soil and water conservation

3 Classification benefit calculation

Soil and water conservation benefits of this standard, including water transfer and soil conservation benefits, economic, social and ecological benefits and other four categories. The relationship between the four are. to produce economic, social and ecological benefits in soil conservation benefits of water transfer basis. Calculation of the content of four types of benefits Table 1. Table 1 Classification and Soil and Water Conservation Benefit calculation content Benefit calculation content classification calculated specific projects Diversion Soil conservation benefit Diversion (a) Increase soil infiltration Change Microtopography increase soil infiltration Increased ground vegetation to reduce the surface erosion Improvement of soil properties increase soil infiltration Diversion (b) Storing runoff Slope of small water impounding projects runoff All around the small water impounding projects runoff Storing surface runoff ditch check dam and reservoir engineering Diversion (c) Slope Drainage Ability to improve drainage slope Diversion (D) The Small Watershed Runoff Adjusted annual runoff Adjusting the dry season runoff Regulating runoff during the rainy season Soil conservation (a) Reducing soil erosion (surface erosion) Change Microtopography mitigate surface erosion Increased ground vegetation to reduce the surface erosion Soil properties mitigate surface erosion Soil conservation (b) Reducing soil erosion (gully erosion) Suppression mitigate gully erosion gully head advancement Suppression ditch cut mitigate gully erosion Suppression mitigate gully erosion gully bank expansion Soil conservation (c) Impounding slope ditch sediment Small water impounding projects Sediment Check Dams library project impounding sediment
