中文摘要	【目的】揭示不同土地利用类型间的养分质量特征,为干热河谷石漠化区土地生产力恢复、土壤科学研究和农业可持续发展提供科学依据。【方法】以干热河谷石漠化地区花椒地、金银花地、火龙果地、核桃地、柚木地和玉米地为研究对象,采用Pearson相关分析和主成分分析法,阐明土壤理化性质在6种土地利用类型间的变化及土壤质量指标间的相关关系。【结果】①干热河谷石漠化地区花椒地的C、N元素含量较低,核桃地、玉米地和金银花地土壤的TP、TK和AK含量较亏缺,火龙果地和柚木地土壤的养分元素均处于较低水平。②经相关性分析,土壤TN含量与pH、AN含量与SOC含量、TP含量与TK/AK含量和TK含量与AK含量均呈极显著正相关;土壤BD与TN含量呈极显著负相关。③土壤质量综合指数为花椒(2. 334) >金银花(1. 283) >玉米(- 0. 330) >核桃(- 0. 386) >柚木(- 1. 153) >火龙果(- 1. 598)。【结论】干热河谷石漠化区在作物栽培与管理过程中应补充N、 P、K等矿质元素,并注重养分作用效应的协同性。
英文摘要	【Objective】The present paper aims to reveal the characteristics of nutrient quality among different land use patterns,and to provide scientific references for land productivity restoration,soil science research and agricultural sustainable development.【Method】The authors took Zanthoxylum bugeanum,Lonicera japonica,Hylocereus undulatus,Juglans regia,Tectona and Zea mays fields as the research object in the dry-hot valley rocky desertification region,and employed Pearson correlation analysis and principal component analysis to clarify the changes of soil physical and chemical properties between the six kinds of land use patterns and soil correlation between quality indicators. 【Result】(i) Contents of C and N in the area of Z. bugeanum in dry-hot valley rocky desertification region was low,contents of TP,TK and AK in the soil of J. regia,L. japonica and Z. mays was relatively deficient. The nutrient elements in the soil of the H. undulates and Tectona land were low. (ii) Correlation analysis showed that significant positive correlation was found between TN content and pH,AN content and SOC content,TK/AK content and TP content,TK content and AK content. However,there was extremely significant negative correlation between the soil of BD and TN. (iii) Comprehensive index of soil quality was Z. bugeanum (2. 334) > L. japonica (1. 283) > Z. mays (0. 330) > J. regia (- 0. 386) > Tectona (- 1. 153) > H. undulates (- 1. 598) .【Conclusion】In the process of crop cultivation and management in dry-hot valley rocky desertification region,we should supplement mineral elements such as N,P,K,and pay attention to the synergistic effect of nutrient supply.
