湖北省江汉流域经济区农业地质调查成果综述

Summary of Agricultural Geological Survey Results in Jianghan River Basin Economic Zone of Hubei Province

通过对江汉流域经济区的区域调查、区域评价、局部评价和总体综合评价等阶段不断地实施推进,取得了一系列重大的科技创新成果和旨在为农业发展服务的科学成果,实现了以地质调查手段为农业经济发展服务的基本目标:查明江汉流域表层土壤及水体化学元素及其化合物的含量和分布特征;对有害、有益元素及其化合物的生态效应进行分析研究,对农作物产地环境和人类生存环境进行评价;发现江汉平原农业生态环境若干重大地球化学问题;开展流域区农业生态环境安全评价与地球化学预警、预测;开展名、优、绿色农产品适宜区地球化学背景研究;开展区域地球化学背景与农业生态环境相关性研究,建立区域农业地球化学评价模型,提出农业经济长远规划和结构调整建议;建立农业经济区地球化学数据库及成果服务系统,为区域农业经济规划、农业结构调整,发展优质、高产、高效、生态、安全农业提供基础资料和科学依据。

By carrying out the regional investigation, regional evaluation, local evaluation and overall comprehensive evauation ol Jianghan Economic Zone, a series ol signilicant achievements in scientific and technological innovation and scentilic achievements aimed at agricultural development have been achieved. The basic goal ol serving the agricultural economic development by means ol geological survey was realized. The contents and distribution characteristics ol chemicelements and their compounds in surlace soil and water bodies in Jianghan Basin were identilied. The paper studied oecological ellect ol harmlul and benelicial elements and their compounds, evaluation ol crop origin environment and human survival environment, lound some important geochemical problems ol agricultural ecological environment in JianghaPlain, carried out agricultural ecological environment security and geochemical warning, prediction and evaluation ol wtershed area, established the evaluation ol regional agricultural chemical earth model, put lorward the agricultural economstructure adjustment and long-term planning proposals. The geochemical database and service system ol agricultural economic zone were established,which provided basic data and scientilic basis lor regional agricultural economic planninadjustment ol agricultural structure,development ol high quality,high yield,high elliciency,ecology and sale agriculture.
