流动沙丘

流动沙丘降雨入渗和再分配过程

Infiltration and redistribution process of rainfall in desert mobile sand dune

与此同时流动沙丘%LAND指数增加了0.42%。

At the same time , the index of % LAND of shift sand dune increase 0.42 % .

结果表明，流动沙丘与其它植被类型相比土壤颗粒较粗，有机质含量贫乏，速效钾和pH也较低，但全氮和速效磷的含量却相对较高；

The soil of moving dune has coarser granule , more total nitrogen and available phosphorus , but less organic content , available kalium and lower pH value .

土壤氮素和磷从流动沙丘到固定沙丘含量有所上升，钾素则变化不大，大部分剖面和层次土壤pH呈微碱性；

N and P are raised from flowing dune to fixed dune , and K is not change great , the PH in mostly profile and arrangement is slight alkalinity ;

与固定和半固定沙丘相比，流动沙丘表面水分（即7～8mm以内的降水）最易在短期内蒸发损耗。

In contrast with fixed and semi-fixed dunes the moisture in the surface of shifting dunes would vapor most likely ( i.e. under 8 mm precipitation ) in a short time .

e.由于丘间地水分条件较好，受风沙活动的影响较小，同时由于流动沙丘和丘间地的不断更替降低了物种之间的竞争强度，就使丘间地具有较高的物种丰富度和物种均匀度。

E. Due to favorable condition of soil moisture , weak activity of wind and sand , and low inter-specific competition intensity resulting from repeated alternation between sand dunes and inter-dunes , the plant species richness and the plant species evenness are quite high in inter-dunes .

固定沙丘土壤种子库含量最大，流动沙丘的最小。

Soil seed bank density in fixed dune was greatest , the least in moving dunes . 3 .

固定沙丘、半固定沙丘和流动沙丘的土壤种子库中植物种类间的相似性系数都比较大。

The similarity of soil seed banks in fixed dune , semi-fixed dunes and moving dunes were bigger . 4 .

流动沙丘固定几年后，沙丘含水量明显减少，甚至出现近乎凋萎的程度。

After fixed for a few years , the original migrating dune moisture will reduce gradually , even to wither .

流动沙丘向半流动沙丘过度的主要植物为差巴嘎蒿、小黄柳和沙蓼。
