Community dominant plants and their ecological niche research is the focus of community ecology research. To explore characteristics desert relationship between them soil factors in Qaidam Basin, to provide a basis for construction plant communities sustainable management natural resources Basin. Taking 13 Qinghai Province as objects, this paper analyzed species based on physical chemical prope...
BACKGROUND The central function of chloroplasts is to carry out photosynthesis, and its gene content and structure are highly conserved across land plants. Parasitic plants, which have reduced photosynthetic ability, suffer gene losses from the chloroplast (cp) genome accompanied by the relaxation of selective constraints. Compared with the rapid rise in the number of cp genome sequences of pho...
desertification leads to decrease in the ecosystem c pool and attendant reduction in soil organic carbon (soc). reclamation of sandy land in arid and semi-arid has a high potential to increase carbon sequestration and improving soil quality. our objective as to examine the changes in the soil carbon sequestration and soil properties of two soil layers (0–20 and 20-50 cm) under two types of recl...
Growth is restricted by both water and phosphorus (P), balancing the relationship between non−structural carbohydrates (NSCs) carbon: nitrogen: (C:N:P) essential for Haloxylon ammodendron to adapt arid habitats. The survival growth strategies of dominant species H. in a desert ecosystem were examined order better serve restoration degraded ecosystems desertification control. Three salt gradient...
Haloxylon ammodendron (C.A.Mey.) Bge. is crucially important for stabilizing sand dunes in the desert area of Junggar Basin and has thus been widely planted oasis–desert ecotone windbreak fixation purposes since 1980s. The spatial distribution structural characteristics plantations three different ages—planted 1983 (36a), 1997 (22a), 2004 (15a)—on southwestern edge Gurbantünggüt Desert were stu...
با هدف استفاده از فضای خالی بین haloxylon ammodendron برای شناسایی و معرفی گونههای مناسب جهت کاشت همزمان باseidlitzia atriplex canescens، salsola rigida از گونه های ،h. ammodendron بوتهای و تقویت اکوسیستم مناطق دارای پراکنشاستفاده شد. نحوه کاشت در قالب مدل آماری بلوکهای کامل تصادفی ، با 3 anabasis setifera و nitraria schoberi ،rosmarinusبلوک (تکرار) و هر بلوک با 6 تیمار در ایستگاه تحقیقات منابع...
