7、，东接天水、西靠兰州、北邻白银，南连陇南，并与甘南、临夏接壤，具有承东启西，南连北展的区位优势。全市辖安定、通渭、陇西、临洮、29渭源、漳县、岷县1区6县，119个乡（镇），总人口296万人，总面积2.03万平方公里。耕地772.28万亩，人均耕地面积2.61亩。气候属温带半湿润和中温带半干旱区，东南暖湿气流受阻，大陆性气候明显，年平均气温5.7—7.7℃，年总降水量400—600mm。定西是古“丝绸之路”重镇，素有“甘肃咽喉，兰州门户”之称，现在是东西大通道的必经之地，陇海铁路和310、312、316、212等国道贯通全境，交通十分便利

8、。正在建设中的兰临高速公路、兰渝铁路和已建成的巉柳高速公路和宝兰铁路复线将会进一步改善交通条件。1.1.2·生态资源定西生态改善，资源丰富，具有广阔的开发前景和巨大的发展潜力。全市生态环境初步
