| 摘 要： | 本文应用哈默尔干旱指数原理,分析了陕西渭北旱原西部地区农田干旱形成条件及发展、结束规律,建立了适合该区应用的气候旱度模式:X_i=Z_i/46.55+0.7248X_i提出了该区农田旱度指数模式:K_z=(P-E_T+S_0-R_0)/160。并探讨了农田抗旱的途径。

| Abstract: | Analyses the formation, development and end of drought in western Weibei dry plateau farmland based on Hammer's drought index. A drought model Xi = Zi/46. 55 4-0. 724 8Xi-1 well applied at that district was derived. A drought index model for farmland Kz= (P -Er+S0+R0)/160 was also derived. Drought control methods were discussed. |
