Abstract The role of livestock grazing in regulating woody cover and biomass grass‐dominant systems is well recognized. However, the way which plant populations respond when are removed from absence other disturbances, such as fire, remains unclear. We conducted a 10‐year, replicated fencing experiment sandy semiarid rangeland northern C hina (which has mean annual rainfall 365 mm), where fires have been actively suppressed for decades. Fencing dramatically influenced growth age structure...
Abstract The density of seeds in soil seed banks and the species composition both aboveground vegetation were examined naturally restored sites (NRS) aerially seeded (ASS) Hunshandak sandlands northern China. Five 1, 2, 4, 8, 15 years ago four 5, 7 ago. In total, 36 recorded bank 41 for all NRS, whereas numbers 17 19, respectively, ASS, indicating that NRS can support higher diversity than ASS. During initial 2 restoration, introduced alien shrubs by aerial seeding dominated although there...
Sparse-elm grassland is the remarkable landscape of Hunshandak Sandland in Inner Mongolia Autonomic Region China. Maximum quantum efficiency (Fv/Fm) 99 native plant species (85 grasses, 11 shrubs, and 3 trees) different functional Types (PFTs) distributed fixed sand dune, lowland, wetland was investigated. Deep-rooted (tree, shrub, perennial grass) had higher Fv/Fm values than shallow-rooted (annual grasses), suggesting that soil drought major environmental stress. Annual C4 grasses annual...
Early production and high energy efficiency are important in greenhouse vegetable cold regions. A dynamic temperature integration strategy with low pre-night (PNT) has been developed to reduce consumption improve early fruit yield use efficiency. However, the application of this control is feasible only if there no crop quality loss. To determine PNT tolerance threshold explore mechanism on plant growth development, effects four treatments (PNT9, PNT11, PNT13, PNT15, an actual 9.4, 11.3,...
The Hunshandake Sandy Land is one of the largest sandy areas in China and closest source sand dust to Beijing Tianjing areas. Sand fixation by vegetation considered most efficient strategy for control sustainable development, so clarifying coverage plant adaptation characteristics helpful guiding restoration improving local sustainability. Here, we investigated growth on mobile dunes specified photosynthesis stomatal pioneer plants fixation. survey showed that windward slopes had far lower...
Abstract Free‐range chicken farming ( CF ) has been demonstrated to be effective in controlling locust plagues and restoring degraded vegetation rangelands. However, the effects of on growth soil conditions rangeland ecosystems are not yet well known. We studied (treated by three stocking rates from low‐intensity high‐intensity), livestock grazing LG zero ZG characteristics nutrient a northern China. significantly improved quality compared with . The moderate 2 333 birds per hectare enhanced...
About one third of the world's land surface is covered with arid and semi-arid areas. It predicted that global warming will increase desertification by 17% before 2050. At present, making approximately 12 million hectares every year useless for cultivation grazing worldwide. Over 250 people earth's are directly threatened (Diallo 2003). China several countries severely affected desertification; almost 90% natural grassland has been to differing degrees (Lu & Yang 2001; State...
The world's arid and semi-arid regions are severely affected by desertification. In China, wind erosion, water soil salinization the freezing melting processes have contributed to 2.64 million km 2 of desertified land, covering 27.5% country's land surface (State Forestry Administration, Peoples' Republic China 2005). Although climate change could be a reason for desertification, anthropogenic factors such as overgrazing overcultivation also contribute degradation in grassland areas...
There are many elm (Ulmus pumila) distributed on the fixed sand dune in Hunshandak Sandland. Elms_motte_veldt is climax community of vegetation succession this region. Recently, quantity elms decreased sharply, especially for young and seedlings, elms_motte_veldt was severely destroyed. In order to reveal reason these changes, three typical sites centre Sandland containing were investigated during August 2001 2002. These represented 3 levels human disturbance: light disturbance (LD) a ley no...
