区域地质调查中农业生态地质研究初探

Researches on Agricultural Eco-geology in Regional Geological Survey

通过山东临淄城幅、青州市幅及河北龙华镇幅、流常幅的 1∶5万区域地质调查开展农业生态地质研究 ,总结出应主要从基础地质调查、土壤地球化学调查、水文地质调查 3个方面与农业生态结合。基础地质地貌条件控制着农业的布局、土壤的地球化学背景 ,且直接关系到农作物的生长环境、营养元素含量等 ;其中水文地质特征是农业可持续发展的关键。

Large scale regional geological survey is carried out in the interests of the public, and should serve the society. Nevertheless, the traditional regional geological survey aims only at the geological research and the discovery of mineral deposits, and hence can no longer meet the need of today's economic development. Based on the agricultural eco geological investigation in the 1∶50 000 geological survey in Linzi and Qingzhou areas of Shandong Province as well as Longhua and Liuchang areas of Hebei Province, the authors have reached the conclusion that the agro eco geological investigation is mainly connected to agricultural eco geology in the aspects of basic geological survey, soil geochemical investigation and hydrogeological investigation. The basic geological and geomorphological conditions control the layout of the regional agriculture and the geochemical condition of the soil, and have direct connection with the growth environment and the trophic element content of the corn. In addition, hydrogeological characteristics seem to be the key factors responsible for the sustainable development of agriculture.
