Through 5 years observation and investigation

the suitable range

plant recovery

sand dune moving distance

investment and production value of ten moving sand plant block models were studied. It is show that precipitation can sustain plant suvival

and plant sand block can be used for harness moving sand. All the ten models are suitable models except squared spread straw-planting Caragana microphylla model and squared sowing straw-sowing Hedysarum mongolicum and Caragana microphylla model are not suitable to upper sand. Different model has different plant recovery speed

sand float distance

investment and production value. From the point of harness effectiveness

Hedysarum mongolicum plant sand block model and Hedysarum mongolicum-Salix flavida plant sand block model arethe best

Salix flavida plant sand block model and Hedysarum-packing model are the second

Salix flavida-packing model

squared straw-planting Hedysarum mongolicum model and squared straw-planting Hedysarum mongolicum and Caragana microphylla model are the third

squared spread straw-planting Caragana microphylla model

squared sowing straw-sowing Hedysarum mongolicum and Caragana microphylla model and squared straw-planting Salix flavida model are the worst. Study results provide a scientific way for harness floating sand.
