| 1. | Influence of soil humidity and vegetation coverage on wind erosion 土壤湿度和植被盖度对土壤风蚀的影响 |
| 2. | Assessment of vegetation coverage factor in soil erosion model based on aster image interpretation 影像的土壤流失方程植被覆盖因子估计 |
| 3. | Soil infiltration and models in different vegetation coverages in guishuihe river basin 妫水河流域不同植被覆盖条件下土壤入渗及模型的比较分析 |
| 4. | ( 7 ) the concentration of dissolved k basically decreases with the increase of vegetation coverage ( 7 )溶解态钾浓度基本随着植被覆盖度的增大而减小。 |
| 5. | With the increase of vegetation coverage , the amounts of slowly available k and rapidly available k lost in the runoff obviously decrease 植被覆盖度增大,缓效钾、速效钾流失量显著减少。 |
| 6. | Vegetation coverage ( slope gradient 20 ) has more effect on the loss of soil , slowly available k , and rapidly available k than slope gradient 植被(在坡度20o64 )比坡度对土壤、缓效钾和速效钾流失量的影响更大。 |
| 7. | Minqin desert area belongs to the typical droughty desert shrubs and its vegetation coverage only comes to 5 % desert climate and its 15 % 摘要民勤沙区属于典型的干旱荒漠气候,植被以灌木荒漠为主,盖度一般只有5 % ~ 15 % 。 |
| 8. | Among the five fusion images the brovey image had the highest classification accuracy , it was 99 . 5 % , and it was high enough for the acquirement of the vegetation coverage of the city 尤其是brovey融合图像提取植被信息的精度达到99 . 5 ,已经能够满足准确提取植被覆盖率的需要。 |
| 9. | When vegetation coverage is 10 % , amount of slowly available k , rapidly available k , and dissolved k lost in the runoff are less 74 . 51 % , 73 . 84 % , and 4 . 66 % than open ground 当植被覆盖度达到10时,缓效钾、速效钾和溶解态钾流失量分别比裸地减少了74 51 、 73 84和4石6 |
| 10. | The method of delphi is used to decide the weight of all environmental factors , among which vegetation coverage is the most important , next is pollution load and water channel density 利用层次分析法定量各指标的权重,表明植被覆盖是影响石河子市生态环境最重要的因素,其次为污染负荷与水网密度状况。 |
