The soil seed bank of a rehabilitated draw-down zone and its similarity to standing vegetation in the Three Gorges Reservoir Area

The reverse seasonal flooding that resulted from the construction of the Three Gorges Project has induced a drastic degradation of draw-down zone vegetation and the seed bank in the reservoir. The composition and distribution of seed banks and their similarities to standing vegetation were determined through field investigations and germination experiments on the vegetation as...

The effects of the reverse seasonal flooding on soil texture within the hydro-fluctuation belt in the Three Gorges reservoir, China

Purpose The formation of the large hydro-fluctuation belt at the altitude of 145–175 m, following the construction of the Three Gorges Dam, developed from the terrestrial system in the Three Gorges reservoir. This research mainly concerned the effects of the resultant reverse seasonal flooding on soil texture. Materials and methods Four field experimental plots were designed with...

Effects of the seasonal flooding on riparian soil seed bank in the Three Gorges Reservoir Region: a case study in Shanmu River

Introduction The water-level fluctuation in the Three Gorges Reservoir Region has changed dramatically as a result of the hydroelectric project for flood control and power generation. The riparian seasonal hydrological environment also has changed from summer flooding with winter drought to summer drought with winter flooding. The changes of riparian seed bank and vegetation were...

Effects of exotic species Larix kaempferi on diversity and activity of soil microorganisms in Dalaoling National Forest Park

Introduction Soil microbial community plays a crucial role in the ecological processes of soil ecosystem. Forest species introduction often changes profoundly soil ecological processes in the forest. Larix kaempferi (Lam.) was introduced to China from Japan as a timber tree species in the 1960s. The activity and functional diversity of soil microorganisms in the L. kaempferi...

Effect of Cynodon dactylon community on the conservation and reinforcement of riparian shallow soil in the Three Gorges Reservoir area

Introduction Riparian vegetation plays a crucial role in soil conservation and riverbank reinforcement. The Three Gorges hydrologic project has significantly changed the pattern of water-level fluctuation and riparian environment, which significantly influenced plant community development and its effect on soil conservation and riverbank protection. Cynodon dactylon, a perennial...
