以崇左市为例的区域自然资源承载力研究

Study on Regional Natural Resource Carrying Capacity in Chongzuo City

通过建立水资源承载力、土地资源承载力、矿产资源承载力的数学模型,探索区域自然资源承载力的计算和评价方法;并以崇左市为例,计算崇左市2010现状年和2015年、2020年的自然资源承载力,然后评价自然资源对区域人口、经济社会发展及发展规模的承载能力。结果表明,崇左市水资源对区域的发展具有较好的承载能力,现状及未来均未出现超载;土地资源承载力中耕地资源承载力的现状已超载,建设用地资源承载力现状及未来均未超载,表明崇左市土地资源承载力存在一定安全隐患;矿产资源中水泥用石灰岩对经济发展的承载能力较强,煤炭和锰矿资源承载力在2015年和2020年均会超载。

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.
