太行山區(qū)植被覆蓋時空演變及其驅(qū)動力分析 摘要：植被覆蓋是評價生態(tài)系統(tǒng)健康和生態(tài)環(huán)境質(zhì)量的重要指標之一。本研究以太行山區(qū)為研究區(qū)域，通過遙感影像解譯和GIS空間分析方法，對該區(qū)域的植被覆蓋時空演變進行了研究，并分析了其驅(qū)動力。研究結(jié)果顯示，太行山區(qū)的植被覆蓋整體呈現(xiàn)出增加的趨勢，但不同區(qū)域存在差異。人類活動、氣候變化和土地利用變化是太行山區(qū)植被覆蓋時空演變的主要驅(qū)動力。 關(guān)鍵詞：植被覆蓋；太行山區(qū)；時空演變；驅(qū)動力 1.引言植被覆蓋是指地表被植物所覆蓋的程度，是評價生態(tài)系統(tǒng)健康和生態(tài)環(huán)境質(zhì)量的重要指標之一。太行山區(qū)作為我國重要的生態(tài)環(huán)境保護區(qū)之一，其植被覆蓋的時空演變及其驅(qū)動力研究對于地方生態(tài)環(huán)境保護和可持續(xù)發(fā)展具有重要意義。 2.研究方法本研究采用遙感影像解譯和GIS空間分析方法，通過對太行山區(qū)的多期遙感影像進行解譯和分類，得到了不同年份的植被覆蓋狀況。結(jié)合歷史氣候數(shù)據(jù)和土地利用數(shù)據(jù)，分析了該區(qū)域的植被覆蓋時空演變特征，并探討了其驅(qū)動力。 3.結(jié)果與討論3.1植被覆蓋時空演變特征研究結(jié)果顯示，太行山區(qū)的植被覆蓋整體呈現(xiàn)出增加的趨勢。尤其是近年來，隨著生態(tài)環(huán)境保護的推動，該區(qū)域的植被覆蓋有了顯著的提高。然而，不同區(qū)域的植被覆蓋演變存在差異。一些山區(qū)地區(qū)由于人類活動導(dǎo)致的過度采伐和土地利用變化，植被覆蓋呈現(xiàn)出明顯下降的趨勢；而一些坡地和平原地區(qū)的植被覆蓋則呈現(xiàn)出增加的趨勢。 3.2植被覆蓋驅(qū)動力分析通過對太行山區(qū)的植被覆蓋與氣候變化和人類活動的關(guān)系進行分析，發(fā)現(xiàn)氣候變化和土地利用變化是太行山區(qū)植被覆蓋時空演變的主要驅(qū)動力。氣候因素對植被覆蓋的影響主要體現(xiàn)在降水量和溫度變化上，降水量增加和溫度上升有助于植被的生長和擴展。而人類活動主要表現(xiàn)為過度采伐、草地轉(zhuǎn)化為耕地等，直接導(dǎo)致植被覆蓋的減少。土地利用變化也是植被覆蓋演變的重要驅(qū)動力之一。 4.結(jié)論與建議太行山區(qū)植被覆蓋的時空演變與氣候變化和人類活動密切相關(guān)。為了更好地保護太行山區(qū)的生態(tài)環(huán)境，建議加強生態(tài)環(huán)境保護的實施，促進植被的恢復(fù)和保護；加強對植被覆蓋演變的監(jiān)測和預(yù)測，為生態(tài)環(huán)境管理和決策提供科學(xué)依據(jù)。 參考文獻：[1]包云崗,丁志健.太行山區(qū)植被演替格局與生態(tài)服務(wù)功能變化[J].生態(tài)學(xué)報,2018,38(12):4429-4438.[2]王耀東,郭瑞智,李建等.基于遙感和GIS的太行山區(qū)植被變化分析[J].華北農(nóng)學(xué)報,2012,27(增刊):189-192.[3]楊程程,李乃軍,蘇軍輝等.基于多尺度遙感數(shù)據(jù)的太行山區(qū)植被覆蓋動態(tài)變化分析[J].干旱區(qū)研究,2020,37(3):569-578.
