- Abstract:
- [Objective]The ecological restoration benefits of typical bryophytes in rock desertification areas were explored to provide data support for further application of bryophytes in rocky desertification management. [Methods] The dominant bryophytes in four types of habitats, such as Hypnum plumaeforme, Anomodon viticulosus, Weisia controversa, Bryum coronatum were selected from four habitats in typical rocky desertification area. The ecological restoration benefits of four bryophytes were comprehensively evaluated based on the entropy power TOPSIS model in terms of saturated water absorption rate, evaporationrate, anti-scouring ability and improvement of soil nutrients. [Results](1)The saturated water rate and evaporationrate of the four bryophytes were significantly different, the highest saturated water rate was the Bryumcoronatum(1384.93%±80.77%)and the smallest was the Weisia controversa(602.74%±34.78%). The maximum average evaporation rate of Bryumcoronatum was 402.43 g/(m2? h, and the average evaporation rate of Bypnum plumaeforme was the weakest with the value of 146.86 g/(m2? h). The saturated water rate(SWR)was positively correlated with pseudoroot density(RD), dry weight(DW), root length of pseudoroot(RLD), the evaporationrate(EV). EV was positively correlated with the RD, DW and SWR, and negatively correlated with the RLD.(2)The overall trend of the effect of the bryophytes on the total nitrogen(TN), total phosphorus(TP), total potassium(TK)and total organic carbon(TOC)contents of the soil was not significant(p<0.005)when compared with the pure soil group after artificially growing bryophytes for a period of 6 months. All of them could significantly improve the activities of alkaline phosphatase(ALP), dehydrogenase(DHO), invertase(IN)and urease(UR)in soil(p<0.005). Principal component analysis(PCA)showed that Anomodon viticulosus had more advantages on soil nutrient improvement than other three bryophytes.(3)Then the scour flow was small, the difference of the anti-scour ability(ASA)of the four bryophytes was not significant, but the ASA was significantly different with the increase of the scour flow; the ASA of Hypnum plumaeform and Bryum coronatum is stronger than the other. The ASA was positively correlated with RD, scour bryophyte biomass(ASA-BOM), RLD, SWR and RC, negatively correlated with IN, and not significantly correlated.(4)Four indicators of SWR, EV, ASA and soil nutrient improvement(ISN)were selected to evaluate the ecological restoration benefits of four bryophytes in rocky desertification area using the entropy weighting method TOPSIS model, and the weights of the four indicators were 21.68%,24.55%,16.84% and 36.93%, respectively. The evaluation results showed that the ecological restoration benefits of Anomodon viticulosus and Bryum coronatum were better in rocky desertification area. [Conclusion] It is suggested that bryophytes of Anomodon viticulosus and Bryum coronatum can be introduced in the ecological restoration and reconstruction to increase the seed source to achieve better restoration benefits.
