| 摘 要： | 研究结果表明 :生长季内 (6～ 9月 ) ,气温变化幅度农田最大 ,林地最小 ;土壤温度 (0～ 2 0cm)差异以裸地最大 ,农田居次 ,林地最小 ;水面蒸发量由大到小排序为裸地 >农田 >林地 ;农田平均空气湿度为 85 .8% ,林地为 73.5 % ,裸地为 6 8.8% ;农田、林地与裸地相比均具有一定的水分涵蓄作用 ,但作物和林木对土壤水分的消耗作用也不容忽视 |

| Abstract: | Results of the study showed that in growing stage (June～September) change of air temperature was more in farmland, and less in forest land ; Difference in soil temperature(0～20cm) was most for bare land, was least for forest land, and for farmland was between the two. Evaporation capacity in water surface was in order: bare land > farm land > forest land; Average air humidity of farmland was 85.8%, 73.5% for forest land ,and 68.8% for the bare. Farmland and forest land have a certain function for water conservation in comparison to bare land, but couldn't be ignored water consumption of crops. |
