大埔?有一片成熟树林，故此是观鸟的好地方。 - 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 ) 。 - The results showed the trend of soil ifi changes was partial " u " , namely , during the course of artificial picea succession , soil ifi decreased sharply at the initial stage , after artificial picea reaches mature forest , soil ifi recovered slowly and reached soil ifi of natural coniferous forest finally
在人工云杉林地中，土壤ifi表现出非正“ u ”型的变化，即云杉幼林向成熟林演替时，土壤ifi迅速下降，大约在云杉40龄出现自疏之后，土壤ifi回升，但恢复速度十分缓慢。 - Based on above - mentioned analysis , the strategy and measures to prevent the soil fertility quality degradation of artificial picea mature forest and improve the stand ecological environment were put forward , including the rational management of inter - cutting down and fostering after artificial picea forest matured . because conifer - hardwood forests generally contain more tree species than pure coniferous forest , and their structure also is more complex , forestation in subalpine of western sichuan should be conifer - hardwood forests
林地土壤有机质主要来源于凋落物的分解，并受其分解速率的控制，解决当前人工成熟林地土壤退化的主要措施应为林地凋落物分解创造条件，即因地制宜地对成熟人工林进行间伐或轮伐，当前在该区域造林应避免营造针叶纯林。
