采用商河县2010年耕地地力评价有机质采样点的数据,运用GIS和地统计学相结合的方法,研究了商河县土壤有机质的密度及储量,并按照土类统计分析了不同土壤类型间的有机碳密度及储量差异。研究表明,商河县土壤有机碳密度范围为1.69~5.17kg/m2,平均3.44kg/m2;有机碳储量为0.26×1010kg。按乡镇统计,有机碳密度最大值为玉皇庙镇3.65kg/m2,最小值为郑陆镇3.15kg/m2,有机碳储量最大值玉皇庙镇3.47×108 kg,最小值张坊乡0.92×108 kg;按土壤类型统计,有机碳密度最大的为湿潮土3.46kg/m2,最小为风沙土3.29kg/m2,有机碳储量最大为潮土10.38×108 kg,最小为褐土化潮土1.34×108 kg。
According to the data of organic matter sampling of cultivated land productivity in Shanghe County in 2010, the density and the reserves of soil organic matter in Shanghe County were studied by the combination of GIS and geostatistics. According to soil statistics, Organic carbon density and reserves differences. The results show that the range of soil organic carbon in Shanghe is 1.69 ~ 5.17kg / m2 with an average of 3.44kg / m2. The organic carbon storage is 0.26 × 1010kg. According to township statistics, the maximum value of organic carbon density is 3.65kg / m2 in Jade Emperor Temple Town, 3.15kg / m2 in Zhenglu Town, 3.47 × 108kg in the largest organic carbon stock, and 0.92 × 108kg in Zhangfang Township. × 108 kg. According to the statistics of soil types, the maximum of organic carbon density is 3.46 kg / m 2 for wet tide soil, 3.29 kg / m 2 for aeolian sandy soil and 10.38 × 108 kg for alluvial soil, and the smallest is cinnamon tide Soil 1.34 × 108 kg.
