基于出山店水库坝址区土壤参数空间分析的植物配置

Plant Configuration Based on Spatial Analysis of Soil Parameters in the Dam Site of Chushandian Reservoir

以出山店水库无人机影像和坝址区62份土壤样本检测数据为基础,使用反距离权重法进行土壤参数空间插值分析,结合坝址区土壤的理化性质,进行坝区生态修复的植物配置研究。结果表明:坝址区土壤酸碱度从南到北大致呈现高-低-高的趋势,未出现强酸、强碱性土壤,适宜多数植物的正常生长;土壤有机质含量属于中等偏下水平;土壤全盐量正常,均属于非盐渍化土壤。植物配置中,在坝址区碱性土壤区域可选择紫叶李(Prunus cerasifera)、榆树(Ulmus pumila)、沙棘(Hippophae rhamnoides)、二月兰(Orychophragmus violaceus)等;中性土壤区域可选择白玉兰(Michelia alba)、西府海棠(Malus micromalus)、栾树(Koelreuteria paniculata)、郁金香(Tulipa gesneriana)等;酸性土壤区域可选择五角枫(Acer mono)、榆叶梅(Ygdalus triloba)、香樟(Cinnamomum camphora)、白三叶(Trifolium repens)等。

Based on the UAV orthophoto and datas of 62 soil samples in dam site area,interpolate spatially about soil paramenters was analyzed by the IDW(inverse distance weighted)method.The plant configuration of ecological restoration in dam area was studied according to the physical and chemical properties of the soil.The results showed that the pH of the soil in the dam site area was proper for plant growth with a high-low-high trend from south to north.There was no strong acid and strong alkaline soil.The content of soil organic matter was at the lower middle level.The content of soil salt was normal and non-salinized.In plant configuration,Prunus cerasifera,Ulmus pumila,Hippophae rhamnoides,Orychophragmus violaceus could be used in alkaline soil area;Michelia alba,Malus micromalus,Koelreuteria paniculata,Tulipagesnerianacould be used in neutral soil area;Acer mono,Ygdalus triloba,Cinnamomum camphora,Trifoliumre pens could be used in acid soil area of dam site.
