Abstract: Spatial distribution and comprehensive evaluation on fertility index in suburb of ZhengZhou, have been studied through combinating the methods of statistics, geostatistics and GIS with the changed Nemoro formula as evaluation model .The results showed a low level of soil available phosphorus, a middle level of soil total nitrogen and a high level of soil pH ,available potassium, CEC and organic matter. The low available phosphorus content may be comparative limiting factors of soil fertility in some area of ZhengZhou suburb. As for the spatial distribution of soil fertility in suburb of ZhengZhou , it also showed that In the southwest and Northeast direction, the comprehensive fertility coefficient of the soil is very relatively low, in the low level by a large scale, among them some higher fertility of the area. Southeast and northwest of direction have the high fertility relatively, in majority good and middle level.
