In order to assess the change of triploid populus tomentoza pulp plantation long-term-site productivity, The paper studied on effects of aboveground litterfall, fine root turnover and wet dust precipitation in nutrient cycling of triploid populus tomentoza pulp plantations at different ages,namely 2a、4a、5a、6a.It studied influence of different factors on decomposition of leaf、tree bark and twig of triploid populus tomentoza to select the operations to accelerate the decomposition and nutrient release. Finally, it studied influence of different intercrops on plantation site productivity and the relationship of intercrops and triploid populus tomentoza to select suitable intercrops. The main results as follows:(1)The aboveground litterfall of triploid populus tomentoza increased along with age from 216.03±59.7gm~(-2) at 3a to 482.38±101.3gm~(-2) at 7a, The N returned by litterfall wasl8.38±2.46kg.hm~(-2)a~-121.63±2.25kg.hm~(-2a~-139.51±4.61kg.hm~(-2a~-138.89±4.89kg.hm~(-2a~(-1) at 3a、5a、6a、7a respectively. The P returned by litterfall was 5.80±0.62kg.hm~(-2)a~(-1)、8.16±0.94kg.hm~(-2)a~(-1), 11.31±1.33kg.hm~(-2)a~(-1)、11.76±1.37kg.hm~(-2)a~(-1) at 3a、5a、6a、7a respectively. The nutrient returned by fine root turnover increased along with age, too. The N returned by fine root turnover was 3.85±0.41kghm~(-2)a~(-1)、5.22±0.63kghm~(-2)a~(-1),7.62±0.89kghm~(-2)a~(-1),9.17±1.22kghm~(-2)a~(-1) at 3a、5a、6a、7a respectively. The P returned by fine root turnover was 0.73±0.07kghm~(-2)a~(-1)、1.69±0.09kghm~(-2) a~(-1)、1.92±0.31kghm~(-2)a~(-1)、1.96±0.21kghm~(-2)a~(-1) at 3a、5a、6a、7a respectively. The leaf was the principal pathway to return nutrient to soil among litterfall, fine root turnover and wet dust precipitation. The proportion of returned N by leaf was 74.84%、71.96%、78.58%、75.03% at 3a、5a、6a、7a respectively,The proportion of returned P by leaf was 85.93%、80.31%、83.04%、83.23% at 3a、5a、6a、7a respectively. Therefore, it is important to protect and utilize the leaf in order to maintenance and enhance the long-term-site productivity of triploid populus tomentoza pulp plantation.

本文采取时序研究法，以3a、5a、6a、7a共4个不同年龄的三倍体毛白杨纸浆林为对象，研究了地上凋落物、细根周转、湿沉降在林分N、P营养元素循环中的作用及不同年龄林分N、P营养元素循环的特征，以评价三倍体毛白杨纸浆林长期立地生产力的变化；采取网袋法研究了不同因素对落叶、树皮、树枝分解的影响，以确定加快其分解、促进养分释放的措施：同时研究了不同间作物对林地影响、林木与间作物之间关系，以选择能维持立地生产力的合适的间作物种类等内容，得到以下结论：(1)随着年龄的增加，三倍体毛白杨地上凋落物的数量从3a的216.03±59.7gm~(-2)增加到7a的482.38±101.3gm~(-2)，通过凋落物归还的N分别为：3a时为18.38±2.46kg.hm~(-2)a~(-1)，5a时为21.63±2.25kg.hm~(-2)a~(-1)，6a时为39.51±4.61kg.hm~(-2)a~(-1)，7a时为38.89±4.89kg.hm~(-2)a~(-1)，归还的P分别为：3a时为5.80±0.62kg.hm~(-2)a~(-1)，5a时为8.16±0.94kg.hm~(-2)a~(-1)，6a时为11.31±1.33kg.hm~(-2)a~(-1)，7a时为11.76±1.37kg.hm~(-2)a~-1随着年龄的增加，通过细根周转归还的养分也在增加，归还的N分别为：3a时3.85±0.41kghm~(-2a~(-1)，5a时5.22±0.63kghm~(-2)a~(-1)，6a时7.62±0.89kghm~(-2)a~(-1)，7a时9.17±1.22kghm~(-2)a~-1归还的P分别为：3a时0.73±0.07kghm~(-2a~(-1)，5a时1.69±0.09kghm~(-2)a~(-1)，6a时1.92±0.31kghm~(-2)a~(-1)，7a时1.96±0.21kghm~(-2)a~-1从地上凋落物、细根周转、湿沉降三种不同途径归还林地养分所占的比例来看，地上凋落物中的落叶是归还养分主要途径，年龄在3a、5a、6a、7a时，通过落叶归还的N所占比例分别为74.84%、71.96%、78.58%和75.03%，归还的P所占比例分别为85.93%、80.31%、83.04%和83.23%。
