- Abstract:
- The aim of this study was to explore the morphological and sedimentary characteristics of Kalidium foliatum Nebkhas in salt lake district. The dunes covered by Kalidium foliatum Nebkhas in the Center of Jilantai Salt Lake in Alashanmon, Inner Mongolia, China, was selected as the studied sites, and the investigation on morphological characteristics of and the grain size characteristics of the surface sediments in two land use patterns was carried out by means of correlation analysis and regression analysis. The results showed that:(1)Kalidium foliatum Nebkhas were all at the primary growth stage in two land use patterns; the density of Kalidium foliatum Nebkhas in non-enclosed area was much higher than that in enclosed area; according to independent sample T-test analysis, there was no significant difference in Hd, V, Ad, L/W between the two land use patterns;(2)the grains of surface sediment were mainly fine sand and very fine sand in research area, but the concentration of grain size in the enclosure area was greater than that in the non-enclosed area; at the same time, the grain size of leeward slope of Kalidium foliatum Nebkhas tends to be finer than that in the windward slope, and the grain size tends to be finer from the foot of slope to the top of slope;(3)under two land use patterns, the grain size of surface sediment of Kalidium foliatum Nebkhas gradually decreases from slope bottom to slope top, the average grain size of windward slope was larger than leeward slope, and sorting of grain size was weak in the dune covered by shrub, therefore, the grain size of sediment was mainly composed of coarse components, and the distribution of sediment particles was relatively dispersed. Therefore, the research results are helpful for quantitative analysis of sand fixation ability of Kalidium foliatum, and provide data for ecosystem protection and restoration in Jilantai Salt Lake area.
