中文摘要	为掌握沙化退耕地植被恢复情况和最佳的适宜该地区的造林模式,以沙化退耕地整治技术及模式选择指导思想为基础,通过对民勤县沙化退耕地植被现状的调查,研究了不同年代沙化退耕地上植物群落的特性,同时分析了沙化退耕地上不同密度下梭梭和柠条的生长状况.结果表明:随着退耕时间的延长,沙化退耕地植物群落逐渐向单一化方向发展,且植被均匀度降低,土地潜在沙化的可能性提高;不同密度下梭梭的生长状况存在明显差异,当造林密度为2m*8m(615株 /hm~2)时,梭梭的生长状况最好;柠条的生长状况受种植密度和土壤质地的影响,同时灌水与否对柠条的生长也有一定的影响.
英文摘要	In order to underst and the recovery of desertification woodl and vegetation res toration and select the best afforestation mode in Minqin area,a survey on desertification woodl and was conducted based on the remediation technology of desertification woodl and and mode selection guidelines.The characteristics of plant communities growing on desertification woodl and from different res toration times were studied, and growth conditions of Haloxylon ammodendron and Caragana intermedia under different densities were analyzed as well.The results showed that with the ab andoned time extension,the plant communities simplified gradually, and the uniformity of plants reduced,while the potential possibility of l and desertification increased.Significant differences of H.ammodendron growth conditions under different densities were found.H .ammodendrongrew best under the 2 m * 8 m (615 plants/hm~2)density.While the growth of C.intermedia was affected by planting density and soil texture, and irrigation or rainfed also had a certain influence.
