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.

图像中的可视化特征在基于内容的图像检索中扮演着重要的角色，将图像进行情感的标注能够对和谐的人—机交互、装潢和基于情感计算等工程作出相应的贡献，但情感有很大的主观性，不同的图像或图像中的不同颜色、纹理、轮廓等会给人不同的感受，而不同的人对同一幅图像也会产生不同的情感感受，这样很难在客观上给一幅图像定位为某种情感。
