Abstract：
Agroforestry (AF) has become an important strategy in reconciling the contradictory requirements of environmental protection and economic development in ecologically fragile areas, and whose multiple ecosystem services provide effective ways to promote the restoration of degraded ecosystems in the region. However, agroforestry ecosystem services (AFES) are usually constrained by their generative elements (vulnerability, structure, function, and ecological assets) and service management-both crucial for informed decision-making which enhances AFES supply capacity and AF sustainable management. Karst rocky desertification (KRD) is a typical case in an ecologically fragile area, and within the KRD region greatly relevant for promoting AFES as a strategy for restoring degraded regional ecosystems and for achieving sustainable development goals. In this study, a total of 164 publications related to AFES that met a set of inclusion criteria were obtained through the Scopus database using the literature review method of searching, appraisal, synthesis, and analysis. From the systematic literature review results, (i) we found that the number of relevant publications generally exhibited a year-on-year growth trend, with AFES generation elements being the most common topic (68.11 % of publications), and service management research being the second most common (31.89 % of publications); (ii) we summarised the main progress and landmark results of AFES generation elements and service management research and explored the relevant key scientific questions; and (iii) the above information enlightened the key improvement areas of KRD control ecosystem within three aspects: natural environment, agricultural development, and human-environment relationship. This study provides agroforestry practitioners and relevant decision-makers with information for improving and managing the supply capacity of AFES, and also presents important insights on the KRD control ecosystem to land degradation restoration technicians.
摘要：
农林业已成为协调生态脆弱地区环境保护与经济发展矛盾要求的重要战略,多种生态系统服务为促进该地区退化生态系统的恢复提供了有效途径。然而,农林生态系统服务(AFES)通常受其生成要素的限制(脆弱性，结构,函数,和生态资产）和服务管理-对于提高AFES供应能力和AF可持续管理的明智决策至关重要。喀斯特石漠化（KRD）是生态脆弱地区的典型案例，在KRD区域内，与促进AFES作为恢复退化的区域生态系统和实现可持续发展目标的战略非常相关。在这项研究中,通过Scopus数据库使用文献综述法检索共获得了164份符合纳入标准的AFES相关出版物,评估,合成，和分析。从系统的文献综述结果来看，(一)我们发现有关刊物数目普遍呈按年增长趋势,AFES生成元素是最常见的主题(占出版物的68.11%)，和服务管理研究是第二常见的（占出版物的31.89％）；（ii）我们总结了AFES生成要素和服务管理研究的主要进展和具有里程碑意义的结果，并探讨了相关的关键科学问题；（iii）上述信息在三个方面启发了KRD控制生态系统的关键改善领域：自然环境，农业发展,和人与环境的关系。本研究为农林从业人员和相关决策者提供了改善和管理AFES供应能力的信息，并向土地退化恢复技术人员提供了有关KRD控制生态系统的重要见解。
