The results showed that the characteristics of the microclimate at theoverwin-tering places for Culex pipiens pallens were warm (temperature≥4. 9°C), moist (RH≥65. 6%),dim(alumination 2. 0~5. 2 lux)and sheltering from the wind (wind speed≤0. 25 m/s),and were utterly different from those of the outdoor weather at the same time.
Accoding to the results of investigation the author put forward aprimary auggestion about the farmhouse microclimate criterion in this region. Winter:The temperature at the center of the room: 8~12℃The vertical or level temoerature variathon: 3℃The temperature variation between night and day: 4~6℃The current: 0.1~0.15m/s. The air hunidity: 30~50%.
This standard provides ventilation volume, microclimate (including temperature,humidity and wind velocity), hygienic requirement of illumination and permissible concentration of CO 2 (cited from GJB 2261-95), and also limited values of air pollutants (including CO, NH 3, H 2S, inhalant particles, total bacterial count) in the tunnel for stationary troops when occupied by personnel.
The soil water content, the needle water potentials, and the gas exchange as well as the chamber micro climate were measured before, during and after the drought period.
In a hot macro environment (Cs-K?ppen), high-quality wine growing is only possible due to the cool "airconditioned" micro climate in the valleys.

The same reasoning is applicable for the temperature of the microcli mate.
The third module, Tas Ambiens, is a robust and simple-to-use 2D CFD package which produces a cross section of micro climate variation in a space.
