Abstract:: Soil fertility is recognized as a comprehensive indicator reflecting soil properties, and is closely related to landform and soil parent material. This article regarded Xiaojiang Basin, Yunnan Province, which is a typical karst faulted basin, as study area to explore the nutrient status of surface soil in karst faulted basin and the influence of landform and soil parent material on it. Distribution of surface soil nutrients of cultivated lands and comprehensive evaluation of soil quality were investigated by using ArcGIS technology, statistical and geostatistical methods. The soil nutrients were abundant, and spatial heterogeneity of those was obvious. The difference in soil nutrient among landform types was not significant, while it among different soil types was significant. Variance analysis showed that soil types had stronger effect on soil fertility than landforms, and the interaction between the soil type and landform had significant effects on AK (p < 0.05) and pH value (p < 0.01). The comprehensive soil fertility among different landforms decreased in the order: karst platform and valley region > deposition plain region > peak cluster-depression region > karst mountain region > karst canyon region, and it among soil types decreased in the order: lime soil > paddy soil > red soil > purple soil. Landforms and soil parent material affect the soil fertility seriously, which means that it is necessary to take reasonable and effective measures to improve soil structure and soil quality depending on soil properties and corresponding environmental conditions.
