Abstract Due to the combined influences of climate change and human activities, the water deficiency and saline-alkalinization of soil are becoming more severe in the Momoge National Nature Reserve (MNNR) in Songnen Plain, China, resulting in extensive vegetation degradation in wetlands. Suaeda salsa acts as a pioneer species in vegetation restoration of saline-sodic wetlands in MNNR because of its high salt-tolerance. The seeding emergence and early growth of S. salsa in natural condition can b...

We compared the ecological characteristics of tussock individuals and populations undergoing natural and artificial restoration in Carex tussock wetlands in the Sun Island in Harbin and identified the relationships between the growth of Carex tussock and environmental factors. Results showed that there were obvious seasonal dynamics in morphological characteristics of C. appendiculata. Tussocks grew rapidly from May to June, peaked in June, and then decreased steadily from July to August. There ...

Soil degradation, a growing problem in the arid and semi-arid area, significantly influences wetland dynamics and nutrient cycling. Using tussock wetlands as objectives, this study aims to explain the effects of long-term soil degradation on plant diversity and dominant species and identify the impacts of long-term soil degradation, growing month, species, and their interactions on plant nutrient stoichiometry in Momoge wetland. Field experiments were undertaken to explore the responses of plant...

Abstract Drought and flood are two common stresses on the growth and photosynthesis of wetland plants. Wetland plants experience the alternating drought-flooding conditions over an irregular time-scale. In order to investigate the effects of hydrological fluctuations on plant growth and photosynthesis, we subjected Carex schmidtii (a tussock-forming species) to five alternating drought-flooding conditions: consecutive drying treatment (D), moist treatment (W) and re-flooding treatments (RT) afte...

Soil moisture is a major driving force of plant community succession in restored meadows. Existing studies mainly focus on diversity-productivity relationships. However, studies which determine the effects of soil moisture on the plant community properties in restored meadows are lacking. In this study, we conducted a chronosequence analysis of the interactions between soil water content variation and plant community properties in meadows following passive restoration (3-, 5-, 9-, 14-, 17-, 21-y...

Abstract In the arid and semi-arid areas, Carex Tussock had deteriorated and disappeared as a result of water deficit and salinization due to human activities and climate changes. A green house experiment was carried out to testify the restoration feasible of Carex Tussock in salinization area. We used a factorial design with two soil conditions (degraded soil occurred salinization and undisturbed soil), two Carex Tussocks (degraded ones resulted from soda-salinization and well ones) and three w...

Abstract Alternating flooding-drought conditions have been shown to be an effective water-saving method to restore wetland plants in arid and semi-arid regions. Carex schmidtii is a critical plant species for the restoration of degraded wetlands in the Momoge National Nature Reserve (MNNR) in northeast China. Comparative studies of plant leaves, under permanent inundation condition (AF condition) and 30 d cycles of alternate flooding-drought conditions (A30), were carried out. Plant leaf morphol...

Abstract As a common plant in the Momoge National Nature Reserve (MNNR), China, Bolboschoenus planiculmis has been acknowledged as a key species in Siberian Crane (Grus leucogeranus) habitat by providing food for this migratory waterfowl. Water shortage and salinization have severely impacted B. planiculmis vegetation in this area. In order to restore the degraded B. planiculmis wetlands, tuber transplantation is tentatively used in MNNR. However, the effects of the abiotic factors on tuber emer...

Abstract Switchgrass (Panicum virgatum L.) adapts to a wide range of environments. It has been successfully planted in a semiarid region of China’s Loess Plateau as a valuable forage species for restoring vegetation of grassland. However, growth performance of switchgrass needs to be further evaluated after establishment. Relationships between switchgrass growth and outcomes of weed control in terms of nitrogen (N) supply are especially not well understood. Field studies were conducted in 5-year...
