氣候型-
( 3 ) 6000 - 5000ab. p, through comprehensive analysis of these proxy climatic substitute indexes indicates : this was a dry and cold period in which the temperature was the lowest and the precipitation was the least ; the vegetation may mainly be forest prairie ; in the early stage of the period appeared yangshao middle culture - the prosperous culture of miaodigou type, and in the late stage there was yangshao late culture - the culture of xiwang village type
P出現了老官臺文化，中後期即本區老官臺文化之後，出現了仰韶早期文化。門） 6000 5000ab p ，綜合多氣候代用指標的分析結果表明：本期氣候為全新世以來溫度最低、降水量最少的最乾冷時期，在這種乾冷氣候條件下，在前期氣候最適宜期發育的森林植被發生了退化，當時的植被可能以森林草原為主。 -
It is accepted that combustible factors ( vegetation, type of forest and ventilation ), temperature, climatic factors ( relative humidity, wind ( speed ) and days of coutinuous drought ), and terrain factors ( slope, aspect and altitude ) considerably affect forest fire, but human burning activity is still considered as the key factor of wildfire
可燃物中林下地被物，樹種和與閉度，氣象因子中氣溫，相對濕度，風和連續乾旱日數，地形因子中坡向，坡度和海拔對林火災害影響較為顯著，但人野外用火行為是導致林火發生的關鍵因素。 -
Acceding to the theory of crop water requirement, maximum potential evapotranspirations are calculated by applying fao penman - monteith method, and then we obtain the water requirement, water balance and water correction factors ect. of main crops ( spring maize, summer maize, spring wheat, winter wheat, cotton ) and different type grasslands, and the space - time distribution regularities of water requirement of cropland and natural grassland are analysed, the result show : the water requirements of same kind crop in different areas are different, water satified degrees are different to different crops in the same area, and water requirement of same crop are different between years for climatic variation ; the water requirements of main crops are increasing from east to west and from south to north, water satified degrees are decreasing from east to west and from south to north. in growing season, there are deficits in crops water supply in most area, so the irrigation is needed to meet the requirement for crop growing normally
根據作物需水的理論和方法，採用計算精度較高的faopenman - monteith方法（ 1998 ）計算了半乾旱區最大可能蒸散，並基於此計算五種主要旱地作物（春玉米、夏玉米、春小麥、冬小麥、棉花）和不同類型的天然草地的需水量、水分盈虧、水分訂正系數等，分析了農田和天然草地水分供需的時空分佈規律，結果表明：不同地區同一種作物的需水量是不同的，同一地區對不同作物的水分滿足程度是不同的，而且同一種作物在同一地區隨著氣候的變化需水量也會有一個年際變化；主要作物需水量由東向西，由南向北遞增，正常生長發育的水分保證程度由東向西，由南向北遞減。
