T/ACEF 154-2024 Ecological Restoration Effect Evaluation Technical Specification for Polluted Sites in Non-ferrous Metal Mines

Scope

Scope: This document specifies the basic principles, evaluation process, construction of evaluation index systems, acquisition of evaluation indicator data, and evaluation of ecological restoration effects for polluted sites in non-ferrous metal mines; Main technical content: Standards for evaluating the ecological restoration effects of polluted sites in non-ferrous metal mines, which are implemented through four steps: (1) Launching the evaluation of ecological restoration effects: Identify the types of plots and form a working group for the evaluation of ecological restoration effects in mines. (2) Construction of the evaluation index system: First, clarify the target layer, criterion layer, and indicator layer of the evaluation to form a preliminary index structure; then determine quantitative evaluation indicators based on the evaluation objectives of the mine; finally, apply different evaluation methods according to the actual situation. (3) Acquisition of evaluation indicator data: First, collect basic data through socio-economic data, natural geographic data, and other materials; then conduct on-site investigations of the pollution and ecological conditions of the site; summarize and analyze the sampling data and measurement data, and some data need to be calculated to finally obtain the evaluation results. (4) Evaluation of ecological restoration effects: First, normalize the indicators of different categories; then assign weights to the indicators through the selected evaluation methods; finally, comprehensively score based on the grading of the ecological restoration effect evaluation index.
