洛河发源于陕西省洛南公社木岔沟,流经陕西省洛南县、河南省卢氏、洛宁、宜阳三县,经洛阳市于偃师县与伊河汇合,称为伊洛河,最后经巩县注入黄河,全长446.9公里,是黄河的十大支流之一。洛河全长410公里,集水面积12,037平方公里。其中陕西境内长121公里,集水面积3037平方公里;河南境内长289公里,集水面积8818平方公里。
Based on study of the geographical environment of the Luohe River basin about 120 soil samples were collected in different geographical units.This paper deals with the background values of metal.element in soil of the basin. After conventional test and statisitcal treatment9 it is found that most of the background values of soils in the basin are in the range reported in the literature at home and abroad.The correlation coefficient matrix of background values is also calculated and the results show that the correlation coefficients of some elements are significant at different levels.This may probably be attributed to the transformation and accumulation processes of these elements during weathering and soil genesis processes.
