摘要:
青海省是长江、黄河、澜沧江的发源地,被誉为“三江源”、“江河源头”、“中华水塔”,同时青海省经济发展水平相对落后,矿产资源经济是青海省主要经济来源之一,在未来一定时期内,矿产经济对GDP的支撑作用仍将难以被其他取代。青海省地处青藏高原,其生态系统十分脆弱,而矿产资源的开发势必会对植被、水资源等生态环境造成严重的破坏。已有不少开展过地勘与开发的矿区,草场退化、水土流失、土壤碱化板结、地表水系枯水期延长、地下水矿化度上升、牧区畜牧能力下降等问题已经显现。因此制定绿色勘查标准并实施势在必行。本文分析了青海省制定实施绿色勘查的必要性,并就实施绿色勘查的技术方法和相应的操作规范进行了探讨,可对青海省的生态环境保护提供有益的帮助。

Abstract:
Qinghai Province is the birthplace of Yangtze River, Yellow River and Lancang River, known as“Source of Three Rivers”,“Headwater” and“Chinese Water Tower”.At the same time, because the economic development level is relatively backward, mineral resources economics is one of the main economic sources, and the supporting role of the mineral economics on GDP will still be difficult to be replaced by others in the near future.Being located in Qinghai Tibet Plateau, the ecologi-cal system is very fragile, the development of mineral resources is bound to cause serious damage to vegetation, water re-sources and other ecological environments.Grassland degradation, soil erosion, soil alkalization and hardening, prolonged dry season of surface water, groundwater salinity increasing and pastoral ability declining have appeared in many developed min-ing areas.In this background, it is imperative to establish a green prospecting standard.The paper discusses the necessity of formulating implementation of green prospecting standard for Qinghai Province and the related operating specifications.
