This document belongs to the same series of standards as the following. Technical Guidelines for Ecosystem Assessment --Standards for ecosystem assessment methods for evaluating ecosystem pattern and quality; --Standards for ecosystem assessment and ecosystem service assessment methodologies; --Standards for ecosystem assessment and terrestrial ecosystem degradation assessment methodologies; --Standards regarding technical guidelines for urban ecosystem monitoring; --Standards for ecosystem survey methodologies in regional ecosystem assessment; --Standards for technical guidelines on ecosystem assessment and terrestrial ecological asset accounting; --Standards for the comprehensive assessment index system and calculation methods of urban ecosystems. This document is closely related to other documents in the series and is the most comprehensive document in the series. The section on "Defining Ecology" in this document... The process of "system type" sets high requirements for the standards of ecosystem pattern and quality assessment methods in the series; while "ecological production" "Physical quantity accounting of goods and services" is a direct application of standards for ecosystem service assessment methodologies. Ecosystem assessment Technical Guidelines for Gross Terrestrial Ecological Product Accounting

1 Scope

GB/T 46869-2025 is the Chinese national standard covering how the gross ecosystem product of a territory is accounted for - putting a monetary value on what land produces without being sold: water regulation, carbon sequestration, soil retention, flood mitigation, pollination and the landscape people visit. GEP is China's counterpart to GDP for natural capital, and several provinces already report it. At 35,000 words this is the technical basis: the categories, the physical measurement of each service, the valuation methods and the reporting. First edition. It was issued on 31 December 2025 and has been in force since 31 December 2025, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document provides the technical process, indicator system, data usage, accounting methods, and accounting reports for the accounting of Gross Terrestrial Ecological Product (GEP). Guidelines for the compilation of the report. This document applies to the accounting of the gross value of terrestrial ecological products in administrative regions at the county level and above. Other terrestrial natural geographical regions may refer to this document for implementation. This document also applies to ecological protection effectiveness assessment, government performance evaluation, ecological protection compensation, ecological environment damage compensation, and business development financing. Ecological resource rights transactions, etc.
