The feasibility of using soil seed bank for natural regeneration of degraded sandy grasslands

چکیده
Desertification in degraded grasslands is manifested through the development of bare sandy patches, which eventually lead to habitat fragmentation. The ability these patches regenerate naturally in-situ soil seed banks not well understood. To fill this knowledge gap, we randomly selected 24 with areas ranging from 19 898 m 2 a desertified grassland Horqin land, Northern China determine whether bank can be used for natural regeneration patches. Species composition and density as aboveground vegetation composition, abundance coverage were investigated. We then determined their relationships characteristics. Our observations showed that studied area had low species richness, depauperate communities. Consequently, local was able provide sufficient source regeneration. This indicated by between vegetation, For an 300 900 , increase richness should main restoration measures. small less than 50 measure. data highlighted different extents desertification, are requiring distinct

Soil Seed Bank and Plant Community Development in Passive Restoration of Degraded Sandy Grasslands
To evaluate the efficacy of passive restoration on soil seed bank and vegetation recovery, we measured the species composition and density of the soil seed bank, as well as the species composition, density, coverage, and height of the extant vegetation in sites passively restored for 0, 4, 7, and 12 years (S0, S4, S7, and S12) in a degraded grassland in desert land. Compared with S0, three more...

15 صفحه اولinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
