| 1 | Comprehensive eco-environmental effects of the shelter-forest ecological engineering along the Tarim Desert Highway显示文摘In this work, we report a comprehensive study about the eco-environmental effects of the shelter forest along the Tarim Desert Highway, including the effects on aeolian environment, soil, micro-climate, biodiversity, and groundwater. The results show that: (1) The movement of windblown sand near the ground surface was affected by the shelter forest. The wind speed and sediment transport rate in the shelter forest decreased by 64%―80% and 87.45%―99.02%, respectively. In addition, there were also significant changes in the sand flux structure, the sand grain size, and the deflation and deposition on the ground surface. (2) Compared to the natural mobile sand, the soil bulk density in the forest area decreased while the total salt content, the total porosity, and the water content increased. In addition, the soil fertility was significantly improved in the forest area, and showed the 'first rapid, then slow' variation pattern. (3) The shelter forest showed positive effects on the micro-climate. Within the 6 m height above the ground, the air temperature in the shelter forest at different heights was lower than that in the mobile sand, while the air humidity was higher, while, the soil temperature was also lower in the shelter forest than mobile sand. (4) The number of soil microbial species increased significantly with the improvement of habitat in the shelterbelt. However, the population of different species was not distributed evenly across the surveyed area. (5) Currently, no significant effects of groundwater-pumping and forest-irrigation water have been found on the groundwater level and its salinity. The variation amplitude of both groundwater level and salinity was at the level of centimeters and 1g/L, respectively. No obvious variation trend has been observed. | LEI JiaQiang LI ShengYu JIN ZhengZhong FAN JingLong WANG HaiFeng FAN DongDong ZHOU HongWei GU Feng QIU YongZhi XU Bo | 2008 | Chinese Science Bulletin2008，53，S2： | 14 |
| 2 | 塔里木沙漠公路沿线地下水流速流向测定显示文摘本文在沿塔里木沙漠公路设置的监测井中,利用日本Alec Electronics公司生产的MODEL GFD4型地下水流向流速计,对塔克拉玛干沙漠腹地的地下水流速流向作了一次测定,结果显示:沙漠公路沿线地下水平均流速为:0.01 cm/min,即52.56m/a;地下水流动方向在沙漠北部主要以ENE方向为主,沙漠中部除个别井点外主要以EN方向为主,沙漠南部尼雅河下游监测井中流向由ENN方向和WNN方向构成,牙通古斯河下游观测井处以ESS方向为主。地下水流动方向的控制因素主要有:盆地总体地形因素、河流流量变化、局部地形因素。 | 范敬龙 徐新文 雷加强 赵景峰 王鲁海 | 2009 | 工程勘察2009，37，8： | 5 |

| 4 | Historical evolution and the effects of ecological management in Tarim Basin, China显示文摘The Tarim Basin, in northwestern China, is the largest continental basin in the world, and hosts desert landscapes as well as extensive oasis agriculture. Many horticultural products come from this basin. However, since the 1950s, frequent river flow interruptions have occurred in the lower reaches of the Tarim River. Thus, the natural ecology of the basin has undergone significant changes because of recent human economic and social activities. In particular, water resource development and utilization along with climate changes have had a significant impact on the area. To prevent further deterioration of the environment, the Central Government implemented a water conveyance project in 2000. Based on this project, Chinese scientists, together with those from overseas, have conducted extensive research on the historical evolution of the area, and the physiological and ecological responses of the natural vegetation around the Tarim Desert Highway. Progress has been made in the areas of environmental protection and ecological conservation. | ZHUANG Li DONG YunShe YIN FeiHu CHEN YaNing | 2010 | Chinese Science Bulletin2010，55，36： | 2 |
| 5 | 塔里木沙漠公路防护林工程抽水的地下水位响应显示文摘为了掌握塔克拉玛干沙漠腹地单井抽水过程中,地下水位的变化过程,为沙漠生态防护林工程可持续供水提供理论依据。通过设置在塔里木沙漠公路防护林生态工程灌溉用第69号水源井处的观测场,观测了一次抽水过程,2个抽水应力期内,观测井中的水位变化情况,确定了研究区域的几个水文地质参数,分析了抽水过程水位变化规律。研究显示:计算所得渗透系数K=13.32m/d;抽水影响半径R=332.04m;给水度μ=5.08%。在2个抽水应力期内,水位急速下降和急速上升过程均可在其开始后的11min内完成,之后转为缓慢变化阶段。停止抽水后,水位可以恢复到未抽水之前的水平,没有引起天然地下水位的持续下降。 | 范敬龙 金小军 雷加强 徐新文 周宏伟 | 2013 | 中国农学通报2013，29，2： | 1 |
| 6 | 基于机器学习模型的沙漠腹地地下水含盐量变化过程及模拟研究显示文摘为了研究塔克拉玛干沙漠腹地的地下水盐分变化规律,模拟地下水盐分变化过程,评价适合该区域的地下水变化规律的模型。通过对研究区蒸发量、降水量、气温、气压、地下水位、地下水电导率数据的统计分析,揭示了地下水含盐量及其影响因素的特征;使用GP模型、GPLVM模型和BP人工神经网络模型以及综合模型,模拟了气候变化和人类活动双重影响下的地下水含盐量变化过程,并评价了模型的模拟结果。研究结果表明:(1)研究区地下水流动系统主要受气候变化和人类活动的影响,地下水位在局部地区随开采过程呈现波动变化。地下水位变化过程与气压的变化规律相一致;而气温和蒸发量的季节变化规律相一致。地下水盐分含量呈上升趋势。(2)GP模型对于地下水含盐量的预测效果最好;GPLVM模型对于已知地下水含盐量条件下,与其他环境因素进行多元回归分析的拟合效果最好。而GP、GPLVM和BP人工神经网络模型的综合模型,对于包括模型训练和模型预测的全体数据集的拟合和预测效果最好。 | 范敬龙 刘海龙 雷加强 徐新文 王桂芬 钟显斌 闫健 | 2013 | 生态学报2013，33，18： | 0 |
