对吉兰泰地区大面积梭梭林天然更新状况研究结果表明：１．吉兰泰地区的梭梭林盖应小、密度低、分布不均匀。林内幼苗极少，幼树不足，幼苗、幼树、成年村之比为０：２４．６：７５．４，天然更新状况不良，其关键为幼苗极少或无。２．对吉兰泰地区梭梭林天然更新不良的原因进行了探讨，结果表明：种子不足和人为活动对天然更新有一定影响，但大气降水尤其是４、５月份的降水缺乏是导致梭梭林天然更新不良的主要原因。３．梭梭种子成苗与水分的关系为：４、５月份种子出苗约需５ｍｍ左右大气降雨，人工降雨则需９ｍｍ，发芽率随水量增加而提高，并受覆沙厚度影响。４．梭梭种子萌发成苗受多种因素制约，沙埋适应的种子与各因素综合作用的数学模型为：ｙ＝３７．１５１＋１．４５９ｘ＿１一０．３９３ｘ＿２＋１．４５４ｘ＿３一１．７８８ｘ＿４＋０．８４４ｘ＿５＋０．１３９ｘ＿６．其中ｙ为出苗率．ｘ＿１为降水量，ｘ＿２为平均气温，ｘ＿３为平均地温，ｘ＿４为平均最高地温，ｘ＿５为日平均蒸发量，ｘ＿６为干沙层厚度。
The results of natural regeneration of large area Haloxylon ammodendron in the Jilantai area show that: 1. The Kailin Tai area Haloxylon forest should be small, low density, uneven distribution. Very few seedlings in the forest, lack of young trees, seedlings, young trees, adult village ratio of 0: 24.6: 75.4, poor natural regeneration, the key is the seedling with little or no. 2. The reasons for the poor natural regeneration of Haloxylon ammodendron in the Jilantai region were discussed. The results showed that the insufficient seed and man-made activities had an impact on the natural regeneration, but the precipitation in the atmosphere, especially in April and May, Update the main reason for the bad. 3. The relationship between seedling emergence and water content of Haloxylon ammodendron seedlings is as follows: the emergence of seedlings in April and May requires about 5 mm of atmospheric rainfall, and the artificial rainfall requires 9 mm. The germination rate increases with the increase of water volume and is affected by the thickness of covered sand. 4. The seed germination of Haloxylon ammodendron was restricted by many factors. The mathematical model of the combination of sand buried seeds and various factors was as follows: y = 37.151 + 1.459x_1-0.393x_2 + 1.454x_3-1.788x_4 + 0.844x_5 + 0.139x_6. Where y is the germination rate. x_1 is the average temperature, x_3 is the average ground temperature, x_4 is the average maximum ground temperature, x_5 is the daily average evaporation, and x_6 is the dry sand layer thickness.
