基于GIS的冀北葡萄种植区土壤养分空间变异研究

结合地统计学和地理信息系统的方法,以张家口市怀来县沙城镇宋家营村"赤霞珠"葡萄种植基地为典型区,研究冀北地区葡萄产区土壤养分空间变异特征,得出该区土壤养分的空间分布格局。结果表明,土壤有机质含量的提高能够促进其他养分的含量;土壤养分呈现一定程度的二阶趋势,符合正态分布;结构性因素和随机性因素在各种养分的空间分布中有不同影响。在测试数据基础上,可以实施土壤管理分区的模式,以提高养分利用率。

Study on Spatial Variability of Soil Nutrients in Grape Planting Regions of North Hebei Based on GIS

Based on geostatistics and geographic information system method,taking "Carbernet Sauvignon" grape planting base in Song Jiaying Village Chacheng Town Huailai County Zhangjiakou City as typical region,the spatial variability of soil nutrients in grape planting regions of North Hebei was studied,the soil nutrient spatial distribution pattern was obtained.The results showed that the improvement of soil organic matter content could promote other nutrient contents;soil nutrient showed a certain degree of two order trend,and obeyed the normal distribution;structural and random factors had different effects on the spatial distribution of various nutrients.Based on the test data,the model of soil management partition could be implemented,which could improve the utilization rate of nutrients.
