Road net density and stations density are two important indications which can reflect the difference in the distribution of urban public traffic facilities , since there is great difference in the lengths of roads and in the number of bus stations per unit area in the urban different location 摘要城市的不同區(qū)位,單位面積所分布的路長、設立的公交站點數(shù)差別很大,故路網(wǎng)密度與公交站點密度是體現(xiàn)公交設施空間分布差異性的重要指標。
( 4 ) analysis of item illustrate that , during the 19 influencing factors , the influences of post facilities maturity , atmosphere noise pollution condition , geologic and physiognomy condition , flood submerge condition and programming qualification have no difference in regions on business land price , the influence of green - belt park and geologic and physiognomy condition have no difference in regions on residence land price , the influence of rout net density and post facilities maturity have no difference in regions on industry land price 項目分析說明, 19個影響宜賓市城區(qū)地價的因子中,郵政設施完備度,大氣噪聲污染狀況,地質(zhì)地貌條件,洪水淹沒狀況,規(guī)劃條件這5個因子對商業(yè)用地地價的影響沒有區(qū)域差異;綠地公園影響度,地質(zhì)地貌條件這2個因子對住宅用地地價的影響沒有區(qū)域差異;路網(wǎng)密度,郵政設施完備度、洪水淹沒狀況這3個因子對工業(yè)用地地價的影響沒有區(qū)域差異。
In order to solve this contradiction , reservoir engineering methods are used to estimate the exploitation process about the block , which including water drive curve method , the correlation experience method , the method of the flow pipe budgetary estimate and the method of well net density . on the basis of these method , the author studied the macrocospical distributing of remaining oil in each layer 針對單元開發(fā)過程中存在的突出矛盾,運用水驅(qū)曲線法、相關經(jīng)驗公式法、流管概算法、合理井網(wǎng)密度法等油藏工程方法對斷塊的開發(fā)歷程進行評價,在此基礎上進行各小層剩余油的宏觀研究。
