學(xué)生探究案例：找出不同等級(jí)城市的數(shù)目與城鎮(zhèn)級(jí)別的關(guān)系、城鎮(zhèn)的分布與城鎮(zhèn)級(jí)別的關(guān)系并試著解釋原因。在此基礎(chǔ)上，指導(dǎo)學(xué)生一步步閱讀書上的閱讀材料，首先說(shuō)明這是德國(guó)著名的經(jīng)濟(jì)地理學(xué)家克里斯泰勒對(duì)德國(guó)南部城市等級(jí)體系研究得出的中心地理論，他是在假設(shè)土壤肥力相等、資源分布均勻、沒(méi)有邊界的平原上，交通條件一致、消費(fèi)者收入及需求一致、人們就近購(gòu)買貨物和服務(wù)的情況下得出的理想模式。然后指導(dǎo)學(xué)生閱讀圖2.14下文字說(shuō)明，理解城市六邊形服務(wù)范圍形成過(guò)程。指導(dǎo)學(xué)生讀圖2.15，找出圖中城市的等級(jí)、每一等級(jí)六邊形服務(wù)范圍并敘述不同等級(jí)城市之間服務(wù)范圍及其相互關(guān)系，從而得出不同等級(jí)城市的空間分布規(guī)律，六邊形服務(wù)范圍，層層嵌套的理論模式。給出荷蘭圩田空白圖，讓學(xué)生應(yīng)用上面的理論規(guī)劃設(shè)計(jì)居民點(diǎn)并說(shuō)出理由，再和教材上的規(guī)劃進(jìn)行對(duì)照。然后給出長(zhǎng)三角地區(qū)城市分布圖和各城市人口數(shù)，讓學(xué)生對(duì)這些城市進(jìn)行分級(jí)，概括每一級(jí)城市的服務(wù)功能、統(tǒng)計(jì)每一等級(jí)城市的數(shù)目以及彼此間的平均距離，總結(jié)城市等級(jí)與服務(wù)范圍、空間分布的關(guān)系？
