- 摘要:
- 岩溶石山地区土地资源可以分为洼地底部干旱平地类、洼地底部旱涝交替平地类、洼地边缘缓坡类、峰丛陡坡类四类。西南岩溶区峰丛陡坡类最多，平地非常少，并且在人类的不合理利用下，坡地和平地的土壤质量发生了退化。根据石山地区土地资源量和质的特点，结合以往的经验教训，提出土地资源在林业上具有开发潜力，宜园地和宜林地分别可以达到0.15 hm2/人和0.23 hm2/人，分别占到土地资源的34%和51%。
- Abstract:
- There are 4 kinds of land resources in karst rock desertification areas,i.e,dry depression flat land,dry-water logged depression flat land,depression side grading land and fengcong steep land.There is a large quantity of fengcong steep land in karst areas of Southwest China,whose quality of soil getting worse because of unfit land use.So the land use must be changed properly.According to the characteristics of quantity and quality of landuse in karst mountain areas,slope land and flat land are more fit to plant fruit tree or herb.The land fit for orchard and woodland reaches 0.15 hm2 and 0.23 hm2 of each person.And the proportions of them reach 34% and 51% respectively.
