摘要
应用土地潜力评价的原理和方法,结合广东省土地资源的实际情况,划分出:耕地(Ⅰ、Ⅱ、Ⅲ等地)的面积为2844254hm2,占全省土地总面积的19.29%,其中限制因素明显的耕地(Ⅱ、Ⅲ等地)占耕地总面积的57.45%;非耕地资源(IV、V、VI等地)所占的比例很大,约为81%。因而,要求在农业持续利用中针对其主要限制因素和程度,采取相应的措施,才能更好地发挥广东省土地资源的生产潜力。
ased on the theory and method of land capability evaluation and the actual situation of land resources in Guangdong province, The land resources are classified into six grades:Ⅰ、Ⅱ、Ⅲ、Ⅳ、ⅤandⅥ.The former three are cultivated lands, while the other three are non-cultivated lands. The area of cultivated lands is 2 844 254 hm2 which is about 19.29% of the total. Among the cultivated lands, 57.45% are lands with obvious limiting factors to agricultural production. The area of non-cultivated lands is much larger, occupying about 81% of the total land area.Appropriate measures should be taken to make better use of the land resources in accordance with the main limiting factors and their degree to sustainable agriculture.
