| 研究桂西资源富集区农业生态系统的区域分异特点，为各分区生态农业的建设与发展提供参考依据。
运用生态学原理和系统科学方法，建立区划指标体系，使用SPSS 软件进行系统聚类分析和判别分析，以县为基本单
元，将桂西资源富集区划分为5 个生态农业区。区划结果表明，中部和南部河谷丘陵区种植业产值比较高，特色经济
作物播种面积大，具有良好的农业发展基础，生态农业初具规模曰而北部、西北部和东部山地丘陵区经济发展较为落
后，粮食作物的种植占主导地位，特色经济作物比重较低。 |

| In order to provide references for construction and development of ecological agriculture, this paper studied
the diversity characteristics of agro-ecosystem in resources-abundant regions of west Guangxi. Ecological principle and
system science method were used to establish zoning index system and SPSS software was employed for cluster and
discriminant analysis. The resources-abundant regions of west Guangxi were divided into five ecological agricultural zones
by county as the basic unit. The zoning results indicated that output value of planting industry was relatively higher and
planting area of special economic crop was large in central and southern hilly valley areas. The agricultural development
foundation was solid and ecological agriculture began to take shape in these areas. In the northern, northwestern and
eastern hilly areas, economic development was relatively backward, planting of crops occupied a predominant position,
while special economic crop took a very small proportion. |
