| 摘要: |
| 为给青藏高原生态大棚的建设提供科学依据和技术参考，运用ANSYS有限元分析软件对青藏高原生态大棚内的空间温度场进行数值仿真，并研究了棚内影响污水处理和蔬菜生长的区域内的温度变化规律。模拟结果表明，在冬季有可能出现的最不利条件下，由于高原的强辐射和大棚特殊的保温效果，晴天该区域内的温度仍能维持在13～22 ℃，阴天温度可维持在10～18 ℃，生态大棚内的温度条件完全能够满足污水处理和蔬菜种植的基本需求。 |

| Abstract: |
| ANSYS software is applied to simulate the space temperature field of ecological greenhouse in Qinghai-Tibet Plateau and study the variant rule of temperature in the main space of sewage treatment and vegetables growing in order to provides a scientific reference to the construction of the ecological greenhouse.The result of simulation shows the temperature can keep at 13-22 ℃ on sunny day and 10-18 ℃ on cloudy day on the worst condition in winter because of the intensive radiation and special insulation heat,which proves that thetemperature in the greenhouse can meet the need of sewage treatment and vegetables growing. |
