隨著城市經(jīng)濟(jì)的快速發(fā)展和城市人口的不斷增加，人類活動(dòng)對(duì)城市環(huán)境質(zhì)量的影響日顯突出。對(duì)城市土壤地質(zhì)環(huán)境異常的查證，以及如何應(yīng)用查證獲得的海量數(shù)據(jù)資料開(kāi)展城市環(huán)境質(zhì)量評(píng)價(jià)，研究人類活動(dòng)影響下城市地質(zhì)環(huán)境的演變模式，日益成為人們關(guān)注的焦點(diǎn)。按照功能劃分，城區(qū)一般可分為生活區(qū)、工業(yè)區(qū)、山區(qū)、主干道路區(qū)及公園綠地區(qū)等，不同的區(qū)域環(huán)境受人類活動(dòng)影響的程度不同?，F(xiàn)對(duì)某城市城區(qū)土壤地質(zhì)環(huán)境進(jìn)行調(diào)查。為此，將所考察的城區(qū)劃分為間距1公里左右的網(wǎng)格子區(qū)域，按照每平方公里1個(gè)采樣點(diǎn)對(duì)表層土進(jìn)行取樣、編號(hào)，并用GPS記錄采樣點(diǎn)的位置。應(yīng)用專門儀器測(cè)試分析，獲得了每個(gè)樣本所含的多種化學(xué)元素的濃度數(shù)據(jù)。問(wèn)題闡述問(wèn)題背景提出問(wèn)題數(shù)學(xué)建模闡述土壤重金屬污染

問(wèn)題背景提出問(wèn)題問(wèn)題闡述問(wèn)題三：分析重金屬污染物的傳播特征，由此建立模型，確定污染源的位置。問(wèn)題二：通過(guò)數(shù)據(jù)分析，說(shuō)明重金屬污染的主要原因。問(wèn)題一：給出8種主要重金屬元素在該城區(qū)的空間分布，并分析該城區(qū)內(nèi)不同區(qū)域重金屬的污染程度。問(wèn)題四：分析所建立模型的優(yōu)缺點(diǎn)，為更好地研究城市地質(zhì)環(huán)境的演變模式，還應(yīng)收集什么信息？數(shù)學(xué)建模闡述土壤重金屬污染
