由于干热河谷地区的地质结构不稳定、土层浅薄、人口膨胀、过度耕种，尤其长达半年的旱季等原因，导致该地区的生态环境处于极端的脆弱阶段。 |
| 6. | We found that the higher midlayer and deeplayer water contents after harvest , the faster alfalfa grew , and , the more quickly covered the bare soil , the more soil evaporation restrained . in this way , the soil could sustain higher shallow soil water contents
即使在平水年和丰水年，在7月之前降水也不能满足苜蓿的正常生长需要，而在7月以后，降水量略大于苜蓿需水量，所以要获得高产必须进行灌溉。 |
| 7. | In the parable of the sower , jesus describes what happens when the seed falls in the shallow soil among the rocks . the soil looks healthy and ready for the seed and the seed prospers for a little while . but as soon as the hot sun comes out , it withers and dies
第二个地方，种子落在浅土石头地里从外面看起来，这土地很好，很适合撒种，但事实上，撒下去的种子只长了一点，当遇上任何困难，当太阳一出来，就无法再生长，还说：我早知道会这样。 |
| 8. | 2 ) fourier amplitude spectrum analysis : ( 1 ) the fourier amplitude spectra decrease with the increment of depth ; and the components of fourier spectrum become complex in near - surface . ( 2 ) the fourier amplitude decrease faster in shallow soil level , and smaller in deep soil level . ( 3 ) compared with the deepest bedrock fourier spectrum , spectral components of higher than 5 hz decrease with depth decrease
2 .地震动傅立叶振幅谱沿深度的变化规律( d随着深度的增大，傅氏谱振幅逐渐减小;越接近地表傅氏谱的频谱成份越多，形状越复杂;傅氏谱振幅值在浅层沿深度的下降梯度较大，在深层下降较小; “土层/基岩”场地的基岩内_匕下两测点的地震动频谱沿深度几乎不变，傅氏谱十分相似; d基岩以上的土层测点，高于shz的高频成分减少。 |
| 9. | The results indicated : ( 1 ) during the jointing stage of winter wheat , the differences of catalase activity among different measures of soil water utilization are significant in shallow soil , in which the catalase activity of furrow planting with straw mulch is the highest and that of row - spacing - reduced and close planting is the lowest ; ( 2 ) the trends of catalase activity versus depth are almost the same for different treatments , looking like an inverse s ; ( 3 ) for furrow growing without mulch , the activity of soil catalase in the furrow is higher than that in the ridge ; ( 4 ) soil catalase activity reflects some effects from different techniques of soil water utilization and may be used as a indicator for micro - eco - environment in the fields
初步分析得出： ( 1 )冬小麦拔节期，采用不同土壤水利用技术的冬小麦田浅层土壤过氧化氢酶活性差异明显，以沟播不盖秸秆处理的过氧化氢酶活性最强，缩行密植处理的最弱； ( 2 )土壤过氧化氢酶活性随深度的变化趋势大体一致，呈反s形； ( 3 )沟播不盖秸秆处理沟中土壤过氧化氢酶活性明显高于垄上； ( 4 )土壤过氧化氢酶对于田间微生态环境具有指示作用，在一定程度上反映了土壤水利用技术对微生态环境的影响。 |
