A test on the soil moisture monitoring with the CE312 thermal infrared radiometer and (:E313 visihle and near infrared ometers was(onduc;ted at Xifeng Agrometeorologic;al Experimental Site on the loess plateau in the east part of Cansu province ra

Water resource is very lack in Qingyang city which is located to resources very difficult to exploit，sustainable development.a saresult   total thercs a great short the central region of Loess Plateau, and existing waof available water resource，and it prevents society economy from water resource and
this paper, and some problems in utilization of water resource were  its utilization status in Qingyang city were surveyed in analyzed combining the local economy and geographical characteristic, and the basic countermeasures of sustainable utilization in water resource were brought forward too.

 Based on acid rain monitoring data of 11 years in Xifeng climatologicaL station, and main pollutant source data samples in north  of  Qingyang  city,  according to  acid  rain  monitoring  standard  made  by  China  Meteorological  Administration,  acid  rain ChaTaCteTlSt1CS  WPTe  analyzed  StatlStlCally.  ReSLI1tS  S110W  that  aCld  Taln  degree  Weakened  Wlth  f1LICtllatlOn  dLITlng  1992 -2000  In Qlngyang Clty and hOOSted Llp dLITlng 2001-2002  WlthOllt COriSldeTlng 1T1f1LIenCe Of  Wlnd adVPCtlOn, the fTeqLIenCy OCCLITTlng aCld Taln In a year deehned  yearly,  the  monthly  aC1d  Ta1n  degTPe  1S  maXlmlnn  1n  MaTCh  and  t}OVPlnher,  PH V 0.4c},  the  freC(Lleney  OCCLITrlng  aCld Taln 1S maXlmlnn Of 24%-3Jr}10 from ALIgLISt t0  t}OVPlnher.  COriSldeTlng the  1T1f1LIenCe Of  Wlnd adVPCtlOn In OT hefOTe  Taln,  the 1T1f1LIenCe of pollutant source in the north on yearly acid rain intensity isn't obvious, but it can  make the frequency occurring acid rain increase m a year mainly in the influence on acid rain degree is marked in October, PH reduced 0.3, the influence on monthly acid rain summer. The study revealed the fact that acid rain exists over
Longdong loess plateau, it has an active meaning occurrmg 1S to cure acid rain harm and to protect ecology environment.
