黄土

Therefore, the currently experimental demonstration projects aiming at harnessing blown sand and exploiting sandy land resources efficiently in China, is reasonable and also feasible, at least, in the north of wind-blown sand area of the Loess Plateau.

因此，目前国家正在实施与推广的防沙治沙与沙地资源高效开发利用试验示范项目，至少在黄土高原北部风沙区是合理的，也是切实可行的。

The soil moisture characteristics, dynamic variation and spatial variation in the fields for 4 soils in the loess area of Gansu province, maximum hygroscopicity, wilting point moisture and water holding capacity were studied. The dynamic variation of soil moisture shows "two peaks -two valleys" type.

对甘肃黄土地区4个土类的土壤水分特征、动态及空间变异规律，以及最大吸湿水、凋萎湿度和持水性能的研究表明，土壤水分动态变异规律呈&双峰－双谷&型，据此在时序上可划分为5个明显的时期：（1）春季增失墒交替期；（2）春夏严重失墒期；（3）夏秋墒情恢复期；（4）秋冬缓慢失墒期；（5）冬季墒情稳定期。

Today, Johnston traveled mountain waves of water, Bi Ye look blue sky, as the "Terrace kingdom" Zhuanglang earth, Wang Shanshan Cui, look to horizon, such as the carved layers of terraced fields, such as plastic, picturesque, and its "hill Hippophae Top hats, mountain terraces wrapped around the waist, side lock pasture dam ridge, Goudi shoes "comprehensive management of the ecological model of terraced fields, making the Japanese come to visit, the Israeli agricultural experts can not help but praise:" This is Zhuanglang people in the Loess Plateau on the well-painted scenery of a charming landscape, it is the world's a miracle!"

如今，走遍庄山浪水，放眼碧野蓝天，被誉为&梯田王国&的庄浪大地，望山山翠，看地地平，层层梯田如雕如塑，如诗如画，其&山顶沙棘戴帽，山间梯田缠腰，埂坝牧草锁边，沟底穿鞋&的生态梯田综合治理模式，使得慕名前来考察的日本、以色列农业专家情不自禁地称赞：&这是庄浪人民在黄土高原上精心描绘的一幅景色迷人的风景画，简直是世界奇迹！&

The very low natural IRSL and GLSL signal levels of about 80-100 photo counts per second, corresponding equivalent dose of less than 1Gy, were presented for most modern samples, and imply that the IRSL and GLSL signal zeroing could be reached during deposition for most of loess and water-laid sediments in North China.

华北地区大多数现代沉积物细颗粒组分的天然IRSL和GLSL信号水平很低，约80-100光子计数/秒，相对应的等效剂量值小于1Gy。这可能表明，华北地区大多数黄土及水沉积物的IRSL和GLSL计时器在沉积过程中可能已基本&回零&。细颗粒IRSL和GLSL的光晒退实验结果也说明这一点。

I pondered for a long time for the wild apricot write such a poem: in March, your hard Zhigan flashing red / bright flowers, full of festivity Yang / first ray of morning breeze in your Zuiwo Hong Hing / The first round of the Rising Sun will be your rainbow dream sublimation / At this point, you do not calm / dry thin soil slopes of the low-lying land is also very attractive / just because you have scattered red cherry / let loess experienced a glorious wedding / apricot, you have a wild wild long plant / plush velvet acid fruit revealed the life experience of your / you're just waiting for June where Tiantiandixiao the / could be your heart is still sealed so bitter / This is what you do, wild apricot / dedication of the fruit, after the dedication of the nuclear / and you are shaking like that golden leaves / quietly falling.

我思索的久了，为野杏树写下这样一首诗：三月，你坚硬的枝杆闪着红光/耀眼的花朵扬满喜气/第一缕晨风醉卧在你的香馨里/第一轮旭日将你的霓梦升华/此时，你不平静/干廋的土坡洼地也很迷人/只因你散落的红樱/也让黄土经历了一次光彩的婚礼/杏树，你着野生野长的植物/毛绒绒的酸果表露出你的身世/只等六月里你甜甜地笑了/可你密封的心仍是那样苦涩/这就是你吗，野杏树/奉献了果，奉献了核之后/你又是那般摇着金黄的叶子/不声不响地飘落。

The precipitation was the main climate factor affecting interannual variation of soil water and land surface evaporation.

陇东黄土高原的土壤干旱化与地表蒸发关系不大，降水的逐年减少可能是土壤干旱化的根本原因。

The precipitation was the main climate factor affecting inter-annual variation of soil water and land surface evaporation.

陇东黄土高原的土壤干旱化与地表蒸发关系不大，降水的逐年减少可能是土壤干旱化的根本原因。

The test result has been described and the causes of differential subsidence on the bottom of test pit have been analyzed from two aspects (deformation of loess collapse and slip and subside of wet soil mass along fracture). On this basis, the article summarized that Surface water and ground fracture in the activities is to promote mutual interaction.

通过对试验的几种不同沉降关系曲线和试坑沉降变形等值线图的描述，文章从可能引起试坑产生不均匀沉降变形的两个方面(黄土湿陷变形、浸湿土体沿裂缝滑移下陷)作了探讨，得出地表水与地裂缝的活动是相互促进相互影响的关系。

The results showed that: planting two crops in a year under the condition of 640 mm annual mean rainfall in the Loess Plateau conduced to the substantial use of solar and water resources in summer fallow, the biomass yield, economical yield and water use efficiency was improved in different degrees, and the material cycle was enhanced.

结果显示：在黄土高原东南部年降雨量达640 mm左右的旱作农田，发展&一年二熟&种植能较好地利用夏闲期的水热资源，不同程度地提高了全年的生物产量、经济产量、水分利用效率，加强了农田物质循环。
