摘要:通過建立水資源承載力、土地資源承載力、礦產(chǎn)資源承載力的數(shù)學模型,探索區(qū)域自然資源承載力的計算和評價方法;并以崇左市為例,計算崇左市2010現(xiàn)狀年和2015年、2020年的自然資源承載力,然后評價自然資源對區(qū)域人口、經(jīng)濟社會發(fā)展及發(fā)展規(guī)模的承載能力。結(jié)果表明,崇左市水資源對區(qū)域的發(fā)展具有較好的承載能力,現(xiàn)狀及未來均未出現(xiàn)超載;土地資源承載力中耕地資源承載力的現(xiàn)狀已超載,建設(shè)用地資源承載力現(xiàn)狀及未來均未超載,表明崇左市土地資源承載力存在一定安全隱患;礦產(chǎn)資源中水泥用石灰?guī)r對經(jīng)濟發(fā)展的承載能力較強,煤炭和錳礦資源承載力在2015年和2020年均會超載。

Abstract: Natural resource carrying capacity is important to the regional development and development scale. Through establishing the mathematical model of water resources carrying capacity, land resources carrying capacity and mineral resources carrying capacity, the methods of calculating and evaluating the natural resource carrying capacity were explored. Then taking Chongzuo as a example, the natural resource carrying capacity that in the year of 2010,2015,2020 were calculated, and the evaluation had been made that between the natural resource carrying capacity and the development. Conclusions were: Chongzuo have relatively large potential of water resources carrying capacity; carrying capacity of water resources don’t overload in present and future; the carrying capacity of cultivated land resources overload in present, and the carrying capacity of construction land resources don’t overload in present and future, these show that the land resource carrying capacity isn’t safe; the mineral resources carrying capacity of limestone has relatively large potential to the economy; the mineral resources carrying capacity of coal and manganese ore will overload in 2015,2020.
Key words: natural resources carrying capacity; water resources carrying capacity; land resources carrying capacity; mineral resources carrying capacity; Chongzuo city
自然資源承載力是指一個國家或地區(qū)自然資源的供給,對該區(qū)域內(nèi)人口、社會經(jīng)濟發(fā)展的支撐力,是可持續(xù)發(fā)展的重要體現(xiàn)。人口、社會經(jīng)濟的發(fā)展依賴于自然資源的持續(xù)供給,可持續(xù)發(fā)展不是不消耗資源,不是使發(fā)展完全擺脫對資源的影響和依賴,而是要將發(fā)展保持在資源可承載能力的限度以內(nèi),又不能使發(fā)展處于停滯狀態(tài)[1]。因此,自然資源承載力對于區(qū)域的綜合發(fā)展及發(fā)展規(guī)模是至關(guān)重要的,人口、社會、經(jīng)濟發(fā)展必須控制在資源承載力之內(nèi),通過資源的可持續(xù)利用實現(xiàn)社會經(jīng)濟的可持續(xù)發(fā)展[2]。研究從水資源、土地資源、礦產(chǎn)資源三方面對崇左市自然資源承載力進行研究,探討區(qū)域人口、經(jīng)濟、社會發(fā)展與自然資源承載力的關(guān)系,促進人口、經(jīng)濟、社會與自然資源的和諧發(fā)展?!?br>
