| 1. | Changes of artificial vegetation growth in shapotou area 沙坡头地区人工植被生长动态研究 |
| 2. | Design of emegratiom , environmental protection , soil and water conservation for shapotou water control project 刘家峡库区水土流失治理现状及防治对策 |
| 3. | Water power plant at chaipingpu in sichuan province and huanghe shapotou in ningxia autonomous region 四川省紫坪铺和宁夏自治区黄河沙坡头的水利枢纽工程; |
| 4. | Impact of anthropogenic activity on landscape spatial pattern dynamics in man - made and natural landscapes in shapotou desert area of ningxia , china 自然景观中人类活动对景观格局动态的影响 |
| 5. | This brought a halt to the moving sand dunes . due to its success , shapotou was named in the world s 500 best in environmental protection schemes 当然,这里缺少喀斯特地貌,而黄土高原上风化的沙丘起伏跌宕,更另有一番雄奇景象。 |
| 6. | Now shapotou serves as the meeting place of the three dragons - the yellow river , the tengger desert and the railway . the spot is also a famous place for sand sliding 宁肯夏这盆“盆景” ,还有一个得天独厚的条件,就是日照时间长,经常是蓝天一碧如洗,具有像美国好莱坞一样成为电影基地的可能性。 |
| 7. | The reproductive strategy of plants in shapotou played an essential role for vegetation stability . high resistance to drought and long life span enableed hedysarum scoparium and caragana korshinski to adapt themselves to the harsh environments 结果表明:在地处干旱半干旱的沙坡头地区,通过机械固沙与植物固沙相结合的防风治沙模式,建立的雨育人工固沙区植被经过多年演替形成的人工?天然植被是稳定的。 |
| 8. | 2 . the structure of artificial vegetation in shapotou region the structure of vegetation usually consisted of a vertical structure and a horizontal structure of vegetation . based on the vertical structure of vegetation , there were three layers of artificial vegetation in shapotou region 2 、植被垂直结构及水平结构:沙坡头地区人工固沙植被垂直结构可分为三个显著的片层结构:灌木片层、草本片层和生物结皮片层。 |
| 9. | 3 . the growth dynamic of artificial vegetation in shapotou region in shapotou area , the growth curve of shrubs was like the form of " s " . the stagnant period of growth was in april , the exponential period of growth was from may to july , the stable period of growth was from august to october 3 、植被生长动态:研究区内灌木植物生长曲线呈s型,生长停滞期在4月左右,生长指数期在5月到7月,生长静止期在8月到10月, 10月前后停止生长。 |
| 10. | As a result , the water utility rate adds up to 0 . 53 , so the conclusion was drown that the water - saving reform project of shapotou irrigation area has great significance to weining regional economy development with technical feasibility , economic reasonableness and remarkable benefits 实施节水改造工程后的灌区灌溉水利用系数可提高到0 . 53 。从而得出:沙坡头灌区节水改造工程技术上可行、经济上合理,效益显著,对宁夏卫宁地区的经济发展具有重大意义 |
