Stand on a base of upper study, this paper choose distribution map of agriculture and stock raising in seven different historical age as basic material, sum up ten agro-geology environmental factors into Loess plateau Area's AEG system, and cover all these factor's component parts map on distribution draft of every period's agricultural and pastrol, then measure the occupying proportion, bring results into fomula of factor information entropy, finally, take average value of ten factor's information entropy in each period as its characteristical AEG system entropy value.

在以上研究的基礎(chǔ)上大黄特黄A片,欧美丰满大屁股，論文選擇黃土高原地區(qū)七個(gè)歷史時(shí)期的農(nóng)牧業(yè)分布圖作為基本資料美女黄色视频的久草视频，將該區(qū)的十個(gè)地質(zhì)環(huán)境要素納入農(nóng)業(yè)環(huán)境地質(zhì)系統(tǒng)中免费看午夜福利在线观看，將其類(lèi)別分布圖與上述農(nóng)牧業(yè)分布圖進(jìn)行疊加量測(cè)亚洲黄色大片免费网，結(jié)果代入要素系統(tǒng)熵計(jì)算公式美女露出隐私的免费入口网站，求得了十個(gè)農(nóng)業(yè)地質(zhì)環(huán)境要素在各個(gè)歷史時(shí)期中的系統(tǒng)熵，對(duì)每個(gè)歷史時(shí)期的這十個(gè)熵值求算術(shù)平均值就獲得了該歷史時(shí)期黃土高原地區(qū)總的農(nóng)業(yè)環(huán)境地質(zhì)系統(tǒng)熵欧美A欧美一级a爰做。
