| Abstract | 目的]对广西壮族自治区的土壤侵蚀现状进行定量分析,分析土地利用类型与土壤侵蚀的关系,为科学防治土壤侵蚀提供决策依据。[方法]以RUSLE模型为基础,引入喀斯特石漠化修正因子M,构建适合广西地区的土壤侵蚀模型。[结果]①2015年,研究区土壤侵蚀模数为135.51 t/(km~2 · a),土壤侵蚀厚度达0.08 mm/a,土壤侵蚀面积2.52*10~4 km~2,土壤侵蚀量3.21* 10~7 t。其中,喀斯特地区土壤侵蚀面积1.86*10~4 km~2,占土壤侵蚀面积的73.81%,占总侵蚀量的31.01%。②土壤侵蚀量占总侵蚀量的大小顺序为:耕地(37.58%)>林地(30.94%)>草地(16.10%)>园地(6.39%)>工矿用地(4.09%)>裸地(2.16%)。[结论]人类活动干扰强烈的土地利用影响全区土壤侵蚀空间分布格局。 |
| Other Abstract | [Objective] This study aims to quantitatively analyze the state of soil erosion in Guangxi Zhuang Autonomous Region,especially on the relationship between soil erosion and land uses and provides a basis for scientific control of soil erosion. [Methods] Based on RUSLE model, the modification factor M of karst rocky desertification was introduced to construct the soil erosion model suitable for Guangxi Zhuang Autonomous Region. [Results]① In 2015,the soil erosion modulus of the region was 135.51 t/(km~2 · a). The soil erosion thickness was 0.08 (mm/a). The soil erosion area was 2.52* 10~4 km~2,and the soil loss was 3.21 X 107 t,of which the soil erosion area of karst area was 1.86 *10~4 km~2,accounting for 73.81% of the soil erosion area and 31.01 % of total soil loss.② The percentage of soil loss from different land uses in total soil loss was: cultivated land (37.58%) > woodland (30.94%) > grassland (16.10%) > garden land(6.39%)> industrial and mining land(4.09%)>bare land(2.16%). [Conclusion] The land use changes induced by human interferences have greatly affected the spatial pattern of soil erosion in the whole area. |
