【摘要】：黨中央在十八屆三中全會上明確指出“五位一體”的戰(zhàn)略,生態(tài)文明建設被提升到國家宏觀戰(zhàn)略政策層面上,這一重要舉措充分表明了黨中央在環(huán)境保護上的改革決心。2014年國家主席習近平在河南視察時提出:當前我國的經(jīng)濟發(fā)展處于一個重要的時期,因此我們必須立足于當前我國經(jīng)濟發(fā)展的實際情況,面對當前的國際發(fā)展形勢,保持一份平常的發(fā)展心態(tài)。因此在生態(tài)文明建設上,也應該立足當前的實際,主觀上主動去適應經(jīng)濟發(fā)展新常態(tài),滿足廣大人民群眾對良好的自然生態(tài)環(huán)境的愿望,加大力度促進綠色發(fā)展新方式。土地作為人類發(fā)展的基礎資源,為人類發(fā)展提供一切物質(zhì)來源,是人類發(fā)展的先決條件。因此土地資源作為國民經(jīng)濟發(fā)展的物質(zhì)載體,其安全問題對區(qū)域可持續(xù)發(fā)展具有重大影響作用。但在人類社會發(fā)展的過程中,人們對土地資源掠奪式的開發(fā),給土地資源造成巨大的破壞,引起土地生態(tài)環(huán)境日益惡化,并嚴重威脅土地資源生態(tài)系統(tǒng)的自身安全和人類社會發(fā)展安全。故此,展開區(qū)域內(nèi)土地生態(tài)安全現(xiàn)狀研究顯得十分的有必要。本文選取武漢城市圈各城市作為實證研究區(qū)域,在實證區(qū)域土地生態(tài)安全現(xiàn)狀分析的基礎上,以經(jīng)濟發(fā)展新常態(tài)為研究背景,并借鑒“壓力-狀態(tài)-響應”理論模型,選取武漢城市圈各城市自然、經(jīng)濟、社會三個層面的25個指標,運用遺傳算法投影尋蹤模型,對武漢城市圈各城市2003-2012年10年間土地生態(tài)安全現(xiàn)狀進行評價,并根據(jù)遺傳算法投影尋蹤模型最佳投影方向值,對影響武漢城市圈各城市土地生態(tài)安全的影響因素進行分析,并在此基礎上對區(qū)域內(nèi)土地生態(tài)安全進行了發(fā)展趨勢研究。根據(jù)土地生態(tài)安全影響因素分析可以看出武漢城市圈各城市土地生態(tài)安全現(xiàn)狀主要受到人口壓力、產(chǎn)業(yè)結(jié)構(gòu)及資源利用的影響,致使土地生態(tài)環(huán)境狀態(tài)日益惡化。運用灰色系統(tǒng)模型對實證區(qū)域各城市2013-2020年土地生態(tài)安全發(fā)展趨勢研究得出期間各城市土地生態(tài)安全發(fā)展狀態(tài)。根據(jù)本文研究結(jié)果表明,武漢城市圈各城市總體而言土地生態(tài)安全狀態(tài)較為樂觀,但是部分城市生態(tài)安全狀態(tài)呈現(xiàn)下滑趨勢。在趨勢預測上,研究表明武漢城市圈各城市土地生態(tài)安全狀態(tài)偶有下滑,但是總體下滑趨勢不大,且長期發(fā)展勢頭走勢良好,土地生態(tài)安全狀態(tài)總體趨穩(wěn)。
[Abstract]:At the third Plenary session of the 18 CPC Central Committee, the CPC Central Committee clearly pointed out the "five-in-one" strategy, and the construction of ecological civilization was promoted to the national macro-strategic policy level. This important move fully demonstrates the Party Central Committee's determination to reform on environmental protection. In 2014, when visiting Henan Province, President Xi Jinping put forward: at present, China's economic development is in an important period. Therefore, we must base ourselves on the actual situation of our country's economic development, face the current international development situation, and maintain a normal development mentality. Therefore, in the construction of ecological civilization, we should also base ourselves on the current reality. Subjectively, we should take the initiative to adapt to the new normal of economic development, satisfy the people's desire for a good natural ecological environment, and step up efforts to promote a new way of green development. Land, as the basic resource for human development, The provision of all sources of material for human development is a prerequisite for human development. Therefore, land resources serve as a material carrier for the development of the national economy, However, in the course of the development of human society, the predatory exploitation of land resources has caused great damage to the land resources and caused the deterioration of the ecological environment of the land. Therefore, it is necessary to carry out the research on the present situation of land ecological security in the region. This paper selects the cities of Wuhan City Circle as the empirical research area. Based on the analysis of the present situation of regional land ecological security, taking the new normal of economic development as the research background, and using the theory model of "pressure-state-response" for reference, this paper selects the natural and economic aspects of each city in Wuhan urban circle. By using genetic algorithm projection pursuit model, 25 indexes of three levels of society are used to evaluate the present situation of land ecological security in Wuhan City Circle from 2003 to 2012, and according to the best projection direction value of genetic algorithm projection pursuit model, The factors influencing the ecological security of urban land in Wuhan City Circle are analyzed. Based on the analysis of the influencing factors of land ecological security, it can be seen that the present situation of land ecological security in Wuhan urban circle is mainly under the pressure of population. The impact of industrial structure and resource utilization, The grey system model is used to study the development trend of land ecological security of cities in the region from 2013 to 2020. According to the research results of this paper, the development status of land ecological security in cities is obtained. The status of land ecological security in Wuhan urban circle is generally optimistic, but the ecological security state of some cities shows a downward trend. In the trend prediction, the research shows that the land ecological security state of Wuhan urban circle occasionally declines. But the overall decline trend is not big, and the long-term development trend is good, the land ecological security state generally tends to stabilize.
