摘要:基于生態文明視角,從生產、生活、生態3個維度選取17個指標建立評價指標體系,采取熵值法確定指標權重,建立綜合評價模型,對2000—2017年廣西桂平市土地利用多功能進行評價。結果表明,桂平市土地利用多功能總體水平不高,呈先降后升的趨勢;土地利用生產功能水平較低,呈先平后升的趨勢;土地利用生活功能水平中等偏上,呈波動上升趨勢;土地利用生態功能水平較高,呈先降后升的趨勢。建議通過采取增加對生產用地的投入、控制生活用地規模、增大保護區的比例等措施來提高土地利用多功能水平。
關鍵詞:生態文明;縣域;土地利用;多功能評價;桂平市

Abstract: 17 indexes from production, living and ecology three dimensions were selected to establish evaluation index system based on the perspective of ecological civilization. Index weight was determined by entropy evaluation method and comprehensive evaluation model was set up to evaluate land use multi-functional of Guiping city, Guangxi, from 2000 to 2017. The results showed that the overall level of multi-functional of land use was not high in Guiping city, showing a trend of first decreasing and then increasing. The level of production functional of land use was not high, showing a trend of first stationary and then gradually increasing. The level of living functional of land use was medium and upward, showing an upward trend of fluctuation. The level of ecological function of land use was relatively high, showing a trend of first decline and then rise. It is suggested to increase the input of productive land, control the scale of living land and increase the proportion of protected areas and other measures to improve the level of multi-functional of land use.

中國生態類型具有多樣性,各種生態系統相互聯系、相互依存、相互影響。而中國的生態環境現狀呈總體在惡化、局部在治理改善,治理能力往往趕不上生態破壞的速度,生態赤字不斷擴大。黨的十九大提出加快生態文明體制改革,建設美麗中國,必須堅持人與自然和諧共生,統籌山水林田湖草系統治理,實行最嚴格的生態環境保護制度。土地利用多功能評價能為科學合理利用土地和統籌安排各類用地,保證生產、生活、生態用地,緩解人地矛盾,為評價區域制定切實可行的土地利用方針、政策等提供參考依據,實現土地利用多功能與可持續利用。
隨著工業化進程加速,資源耗竭、環境污染、生態退化等問題日益凸顯,人類開始探索保護環境和可持續發展[1-3]。……
