摘要: 以贵州花江峡谷为例,研究了该地区不同小生境的小气候日变化规律,分析了不同小生境地面温度、气温、光照强度和大气相对湿度的变化特点。结果表明:土面土温高,但温度变化缓和,气温、光照条件和湿度条件都较好,因而土面有利于植物的生长,提高光合产率。石沟土温、气温和光照都较低,相对湿度高,植物的生长相对土面较差。而石槽则小气候变化剧烈,植物生长受到制约。图8表1参12Abstract: Diurnal variation of microclimates in different microhabitats had been studied,and variation characteristics of soil surface temperature,air temperature,intensity of illumination and air relative humidity of different microhabitats had been analyzed in Huajiang valley area. The results showed that soil surface temperature was higher than stone gully and stone pit,but its temperature changed mildly,and air temperature,intensity of illumination and air relative humidity were good,so soil surface was suitable for plant growth and improving photosynthesis rate. However,soil surface temperature,air temperature,intensity of illumination of stone gully were comparatively lower,its temperature and air relative humidity were very good,plant growth was worse than that on soil surface. For stone pit,microhabitats changed dramatically and plant growth was restricted.[Ch,8 fig. 1 tab. 12 ref.]
