中文摘要	为了研究不同植被类型对沙区土壤的改良效果，调查沙区土壤的养分状况，笔者对青龙湾沙区不同植被类型的土壤有机质、有效氮、速效钾、有效磷等指标进行分析。结果表明，青龙湾沙区土壤pH值范围为7.40~7.72，土壤呈中性略偏微碱性;土壤有机质、有效氮、有效磷及速效钾含量偏低。有机质含量对于土壤其他营养元素的含量和有效性均具有比较大的影响。不同植被类型对沙区土壤的改良具有一定的差异，除农田外，果园、毛白杨刺槐混交林的改良效果较好，小叶杨林改良效果较差。总体来说，经过生态林改良后的土壤养分状态得到明显改善。
英文摘要	In order to study the influence of different plants on the effect of soil in desert area and analyze the soil nutrients, the soil samples were collected from different plants in Qinglongwan, nutrient content were analyzed by organic matter, available nitrogen, available phosphorous, potassium. The results showed that the pH value was 7.40-7.72, soil showed slightly alkaline. The content of organic matter, available nitrogen, available phosphorous, potassium were relatively low. The content of organic matter had great effect on the contents and availability of other nutrients. The effect of different plants to protect and improve soil were different, the effect of the orchard and the mixedPopulus tomentos-Robinia pseudoacacia forest was best, Populus simonii at last, except farmland. Generally speaking, the soil physical property in soil was obviously improved after modified by ecological forest.
