- Halosere a plant community in a succession that starts on land periodically inundated by the sea . haloseres include salt - and flooding - tolerant pioneer communities on mudflats and saltmarshes
盐生演替系列：是一种在周期性被海水淹没的陆地上进行演替的植物群落。它包括那些在泥滩和盐沼上生活的耐盐耐淹的先锋群落。 - In preliminary vegetation succession from abandoned land community to herbage community , the increasing degree is higher . and with further succession which is herbage - shrub - early forest - liaotungesis forest community it goes down gradually . ( 2 ) the water content in 0 - 5cm soil layer increases significantly and the water content in > 5cm soil layer decreases in the course of vegetation succession
演替初期(弃耕-地先锋群落草本群落)有机碳含量的增加幅度较大，而后，随植被的进一步演替(草本群落灌丛群落早期森林群落辽东栎群落) ，有机碳含量增加幅度变小。 - In different phases of development , vegetation systems in this region have changed from pioneer herbage species initially recovering in abandoned cropping lands ( bothriochloa ischemum , artenmisia giradii and stipa bungeana , artenmisia sacrorum , spodiopogen sibiricus and sophora flavecens , themeda japonica , and arundinella anomala ) to secondary shrubs ( hippophae rhamnoides , sophora viciifdia , and ostryopsis davidiana ) , early forest community ( populus davidiana , betula platyphylla and platycladus orientalis with arbors or shrub assembling ) , and finally liaotungesis community as the mature forest . in this study , soil profiles ( 0 - 5 , 5 - 15 , 15 - 25 , 25 - 35 , 35 - 50 cm soil layers ) were selected from typical vegetation systems representing for vegetation successions in the region
该区北部目前还保存有空间上完整的植被正向演替系列，即弃耕地先锋群落草本群落(白羊草bothriochloaischemum 、茭蒿artenmisiagiradii +长茅草stipabungeana 、铁杆蒿artenmisiasacrorum 、大油芒spodiopogensibiricus +苦参sophoraflavecens 、黄菅草themedajaponica或野古草arundinellaanomala )灌丛群落(沙棘hippophaerhamnoides 、狼牙刺sophoraviciifdia 、虎榛子ostryopsisdavidiana )早期森林群落(乔灌群聚、山杨populusdavidiana 、白桦betulaplatyphylla 、侧柏platycladusorientalis 、 )辽东栎群落( quercusliaotungensis ) 。 - Organic c in the soil profiles were measured as in total and fractionated into microbial biomass - c , water - soluble organic - c , light - fraction organic - c , and heavy - fraction organic - c . the amounts of microbial biomass - c , and water content in soil profiles were consistently analyzed . the aim of this study was to investigate interactions between the accumulation of soil organic c and vegetation successions in the region , in a purpose to improve understanding on how changes in soil conditions affect vegetation successions in the region
通过分析植被演替各个群落(弃耕地先锋群落、草本群落、灌丛群落、早期森林群落、辽东栎群落) 0 50cm深度内土壤有机碳、微生物碳、水溶性有机碳、轻组有机碳、重组有机碳的变化规律及相互关系，初步探讨了植被正向演替过程中土壤有机碳的积累与变化规律。
