沙丘治理试验研究

Experimental Study on Harnessing Sand-Drift

对南昌县岗上乡兴农村治理风沙化土地试验区流动沙丘的治理进行了研究，提出采取乔灌草并举的办法．在流动沙丘东西向每隔40m栽一条芭茅带，在芭茅带中间栽蔓荆和湿地松；半固定沙丘主要营造混地松固沙林，试验区经11年治理，不仅试验区内流动沙丘和半固定沙丘变成固定沙丘，而且沙丘上林分蓄积量达1893．4m3，折合现值672929元．

Demonstration area of harnessing wind-blown spread sand and harnessing running sand-drift were studied,in Xing village of Ganshang of Nanchang the method of promoting simultancously plantation of arbor, shrub and grass was presented. In running sand-drift there was a fragrant couchgrass ribbon every 40 metres in west-east directionl among the fragrant eouchgrass ribbon planted vitex trifolia and Pinus elliottii; in semi-fixed sand-drift built mainly Pinus elliottii to fix sand-drift. After eleven years harnessing, fixed sand-dirft was formed not only in Demonstrationl running sand-drift and semi-fixed sand-drift, but forest stand storage volume in the sand-drift reached 1 893. 4 m3, It amounted to 672 929 yuan.
