黄土高原

Soil erosion in the loess plateau, is great environmental problem at present, and soil erosion monitoring is of great significance for stipulateing the countermeasures against soil erosion.

在我国，黄土高原的土壤侵蚀是目前举世瞩目的环境问题，土壤侵蚀监测对土壤侵蚀防治对策的制定具有重大意义。

Soil erosion is the most serious ecological environmental problem in Loess Plateau of China. Unreasonable land use practice is identified as one of the most important reasons for triggering and aggravating soil erosion, and the driving mechanisms for land use change and the relationship between land use spatial pattern and soil erosion are the important aspects for the study about soil erosion.

水土流失是黄土高原地区严峻的生态环境问题，不合理的土地利用是引发和加剧水土流失的重要原因之一，土地利用变化驱动机制和土地利用空间格局与水土流失关系是其研究的重要方面。

Grain makings billabong, build grow line of business 3 yuan of structures are the inevitable choice that solves problem of loess plateau commissariat.

粮料分流，建立种植业三元结构是解决黄土高原粮食问题的必然选择。

Becomes silted up field dam as originally create prevent and cure run-off of soil important engineering measure in loess tableland area people crowd long-term practice, at ameliorates ecological environment and agriculture production condition, constructs stable production high yield basic farm, adjusts village industry structure, high power takes advantage of water resource, consolidate quit plough give back forest, gives back grass harvest, promotes rural economy develop wait for aspect, too exert most important effect.

淤地坝作为黄土高原地区人民群众长期实践中独创的防治水土流失的重要工程措施，在改善生态环境及农业生产条件、建设稳产高产基本农田、调整农村产业结构、高效利用水资源、巩固退耕还林、还草成果、促进农村经济发展等方面，也发挥着极其重要的作用。

Because distribution of annual rainfall amount year by year,are cruelly nonuniform,soil water resources are basically important on the growth and development of plants.

土壤水是重要的生态水源和水文要素之一，黄土高原位于干旱半干旱地区，降水量的年际变化大和季节分配极不均匀，土壤水资源对植物生长发育的影响尤为重要。

Since 1999, with the realisation of the grand reconstruction of the ecological environment with the new policy of "Defarming and Reafforestation", human settlements on the Plateau have been transformed into a brand new historical period.

目前，我国社会经济发展水平的不断增长，城镇化建设的速度加快，加之国家1999年来退耕还林生态建设的广泛实施，使得黄土高原的人居环境正面临其重要的发展变化时期。

This paper discussed the significance of eco-economic regionalization of the Loess Plateau as reported in existing literature.

在概述生态经济分区现状的基础上，提出了在黄土高原进行生态经济分区的重要意义。

Through adopting the integration of scale-down an d scale-up or SCS paradigms, the relationship between landscape pattern and s oil nutrient flux in Chinese loess plateau was evaluated.

采用SCS范式，评价了黄土高原地区景观格局与土壤养分流动的关系。

Soil was found to be a slight carbon sink during recovery processes in the agro -pastoral area of the northern Loess Plateau with SOCD, being （2.11 kgCm-2） in scrubland 〉（1.95 kgCm-2） in secondary m-2 ） in artificial grassland 〉（ 1.69 kgCm-2 ） in abandoned farmland and 〉（1.68 kgCm-2） in farmland.

以黄土高原北部水蚀风蚀交错带地区不同生长年限的紫花苜蓿人工草地及其退化后形成的次生草地为主要研究对象，探讨了SOCD的动态变化特征。

In addition, with the progress of runoff scouring, the form of soil erosion changed from sheet erosion to rill erosion.

李勇等(1991)和李勇(1995)通过对黄土高原地区乔灌植被根系与土壤物理性质关系的研究，证

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
