承德壩上地區(qū)晚更新世以來(lái)環(huán)境變化與植被群落土壤含水狀況研究

承德壩上地區(qū)晚更新世以來(lái)環(huán)境變化與植被群落土壤含水狀況研究摘要：本文對(duì)承德壩上地區(qū)晚更新世以來(lái)的環(huán)境變化及其對(duì)植被群落土壤含水狀況的影響進(jìn)行了研究。采用地貌、植被和土壤分析等方法，結(jié)合化石和碳同位素分析等技術(shù)，綜合分析了該地區(qū)環(huán)境隨時(shí)間演變的變化規(guī)律，以及植被、土壤含水、氣候等因素之間的相互作用關(guān)系。研究表明，承德壩上地區(qū)晚更新世演化過(guò)程中，植被與土壤含水量是相互關(guān)聯(lián)的，并且植被群落與環(huán)境條件之間存在著顯著的關(guān)聯(lián)關(guān)系。此外，氣候變化也是該地區(qū)環(huán)境演變的主要驅(qū)動(dòng)力之一。本文的研究對(duì)于深入探討承德壩上地區(qū)生態(tài)環(huán)境的演變規(guī)律和對(duì)策具有重要意義。
