Understanding the driving factors of soil multifunctionality is great significance for protection and restoration degraded terrestrial ecosystems. However, effects above- belowground are rarely evaluated simultaneously, mode both on not clear. Here, we mobile dunes threatened by desertification through aerial seeding, that is, sowing seeds devices, from 1983 to 2015 in Mu Us Desert, China, usin...
The arid regions are fragile and sensitive ecological environment and are vulnerable to desertification. This critical area around arid region where desertification occurs determines the ecological stability of the deserts. In order to combat desertification and decreasing its risks, the restoration projects using varieties of plant species were applied that could change the soil properties and...
Understanding the efficacy of passive (reduction or cessation of environmental stress) and active (typically involving planting or seeding) restoration strategies is important for the design of successful revegetation of degraded riparian habitat, but studies explicitly comparing restoration outcomes are uncommon. We sampled the understory herbaceous plant community of 103 riparian sites varyin...
Zhang Y., Feng M.M., Yang J.Y., Zhao T.N., Wu H.L., Shi C.Q., Shen Y. (2015): Effects of soil cover and protective measures on reducing runoff and soil loss under artificial rainfall. Soil & Water Res., 10: 198–205. The hazards from wind, sand, and soil erosion caused by human activities, such as residue slopes in abandoned urban mines, have resulted in a vicious circle of environmental degrada...
The mountainous massif of Sicó, in the centre of Portugal, is an extensive area composed of calcareous Jurassic formations. Hillside calcareous soils, with high pH, present chemical restrictions to support plant growth and are subjected to important erosion processes leading to their degradation if not protected by vegetation. In a first year of study some soil physicochemical characteristics h...
Parthenium density and species richness were found to be more in non-invaded (N-I) sites as compared to invaded (I) sites of Jaunpur district. pH, OC and %N of the soil indicates that the plant survive naturally at higher level of salinity. In pot experiment, plant growth, proline content, TSS content, chlorophyll, N, P and K was not significantly affected up to 1% NaCl (w/w) over the control a...
The purpose of this research was to investigate the interaction between the type of management approach and the type of combating desertification projects on soil fertility function and it is especially important in monitoring and evaluation of these projects. For this purpose, at the first, the range of three types of combating desertification projects including bush planting, constructing a c...
INTRODUCTION Ecological restoration is a rapidly growing field of biology. Grassroots restoration activities have a long history and have recently increased dramatically. These are now being supplemented by state and federally sponsored restoration projects reaching tens and hundreds of millions of dollars, like those in the Everglades, Lake Tahoe, and the Sacramento River and Delta. Academic p...
