提高土地生產潛力一方面要調控降水,加強基本農田建設,興修水利,應用集流節水技術,發展灌溉農業;另一方面要改良土壤,培肥地力。Obviously, natural soil fertility conditions affect the yield potential but in general, well drained soils with medium to high fertility have the potential to produce high yields

尤其全球變化、區域水分平衡、碳平衡和區域旱災預報等等都需要定量的地表通量信息(輻射通量、顯熱通量、潛熱通量、土壤熱通量) 。顯然,這些通量均要求區域分佈的而不是單點數據。In all types of soil, lateritic red earth covered over 70 % of the total area, ranking first
水稻土有較長耕作歷史,並已形成了潛育層和瀦育層,但土壤肥力並不高。Evaporation varies from evaporation capability, embedded depth of groundwater is more easy, the effect is more obvious ; evaporation capacity decreases if embedded depth of groundwater become deeply, and close to zero under the some depth ; evaporation capacity of different soil texture is different. at ordinary situation, if embedded depth of groundwater is easy, evaporation capacity of the wide and grit soil is powerful ; if embedded depth of groundwater is deep, evaporation capacity of the slender and viscosity soil is powerful
潛水蒸發隨大氣蒸發能力的變化而變化,且潛水埋深越淺,受其影響越明顯:潛水蒸發隨潛水埋深增加而減少,在某一埋深以下潛水蒸發接近於零:不同土質其潛水蒸發量不同,一般情況下,在潛水埋深較小時,土質較粗、偏砂性土壤潛水蒸發較大;當潛水埋深較大時,土質較細、偏粘性土壤的潛水蒸發較大。In the case of canola, as with canadian experience, observations in the field indicate that it requires high rates of sulphur, at least in southern nsw and victoria
用其與小麥相似的研究方法,根據土壤有效水分評估了豆科糧食作物、羽扇豆和紫花豌豆的產量潛力。Beven 18 suggested that when it is applied in its original form to a river basin with thin soils over an imperme - able base, the quasi - steady state approximation holds. however, he also noted that for a variety of alternative transmissivity profiles, or when the saturated depth of the aquifer is large, the deviation in the actual shape of the water table from a steady - state shape can be both large enough and last long enough to call into question the assumption of quasi - steady dynamics
Beven 18也也指出這種「擬穩定」的地下徑流機制雖然能夠較好地應用於那些不透水層之上的土壤厚度比較薄的流域,但對于那些非飽和土壤層的厚度隨空間的變化較大也就是地下水位的變化比較大,或者潛水面的厚度較大的流域,使用這種「擬線性」的topmodel地下徑流機制就容易產生問題Subsurface runoff is obviously closely related with soil water movement in the unsaturated soil zone and dynamic change of the groundwater table. there - fore, it is necessary to develop the subsurface runoff model with a physical base associated with recharge on the aquifer and total storage in the reservoir. also a soil model with a dynamic representation of the groundwater table makes it possible and reasonable to represent a more logical subsurface runoff parame - terization
地下徑流顯然與非飽和土壤層中的水分運動以及地下水位的動態變化密切相關,因而有必要發展考慮土壤含水量與潛水面science in china ser . d earth sciences 376中國科學d輯地球科學第36卷水分通量以及地下水位動態變化的土壤水模型相適應且具有物理意義的地下徑流模型;同時地下水位動態表示的土壤水模型也為發展更為合理的地下徑流模型創造了很好的條件Its soil is suited to growing all forms of food and commercial crops for domestic consumption and export and its numerous inter - island bodies of water offer much potential for island or culture fishing
其土壤適合種植各種食物的經濟作物供國內消費和出口,並且,島嶼之間的水域提供了開發海產養殖的巨大的潛力。Studies show that this time - dependent wall displacement is mostly likely due to undrained creep of clayey soils surrounding the excavation

( 2 )滿水蒸發餐大小與大氣蒸發能力、土壤質地和潛水埋深等因素有關。The saline concentration in the 0 - 40cm layer will produce desalination trend in the 2010. however, the saline concentration in the 40 - 70cm will be slightly accumulated
總體上節水改造工程對灌區淺層土壤鹽堿化改善與防治有積極效果,但中層仍存在潛在鹽漬化的可能。Traditionally, the saturated zone is modeled as a simple lumped continuity equation :, dsitqsdt where t is time, s is the total storage in the reservoir, i is the spatially integrated volume of incoming wa - ter, and q is the discharge subsurface runoff which only depends on the total storage s. this kind of subsurface runoff model has many different parame - terizations 10 12, however it has a very common char - acteristic that the subsurface runoff is just a sin - gle - valued storage - discharge function
對于大尺度水文模型而言,目前常常採用的是集總式的地下徑流機制,其連續性方程一般可表示為d , dsitqst ? 1這里t是時間, s表示整個流域潛水面土壤層的飽和區域總的水分儲存量, i t表示t時刻土壤的非飽和區域向整個潛水面的水分補充量, q s表示僅依賴於水分儲存量s的地下徑流量量分享友人
