Abstract： [Purpose/significance] This paper aims to explore the effectiveness of Altmetrics in revealing the impact of academic books, and then put forward reasonable suggestions for academic book evaluation. [Method/process] Four Altmetrics indicators, Twitter reference, Mendeley reading, text review and libcitation are collected. After analyzing the coverage, quantiles and other statistics of books, the correlation between book citation and Altmetrics indicators is carried out. Books of high indicator values are evaluated from the aspects of published year, discipline and subject in order to explore the application of these indicators in the use of book impact evaluation. [Result/conclusion] The low correlation between book citation and Altmetrics indicators shows that Altmetrics can be used as a new perspective for evaluating academic books, and different Altmetrics indicators reveal different dimensions of book impact. It is suggested to combine Altmetrics indicators and citation and make more use of the characteristics of books such as year and discipline in the future research of book impact evaluation.

Abstract：森林水源涵养功能作为森林生态系统服务的一个重要方面，在国内的研究已有数十年的历史。多数研究中将森林水源涵养功能狭义地等同于森林对降雨的拦蓄能力或对径流的调节能力，而忽略了其对各水文过程的整体性作用以及对气象和土壤因子的综合性影响。此外，在不同研究区域中，对于森林水源涵养功能的理解和研究方法往往一概而论，并未考虑研究区域的自然条件特性和社会经济特征，这使得研究结果的区域针对性不足，限制了对其进一步的应用推广。针对上述问题，在全面分析森林水源涵养的含义和特征之后，定义了不同区域的水源涵养功能内涵和主导服务，并给出了不同区域森林水源涵养功能的适宜计算方法，以期为不同区域森林水源涵养功能的全面提升和水源涵养林生态修复工程提供科学依据。
