的山地不得发展种植业。（2）间接的影响海拔高度热量差异农作物分布的垂直变化3、土壤（包括土壤肥力、酸碱度、土层厚度、土壤结构等）4、市场影响农业生产的类型和产量5、交通运输 6、政策提供或降低某一农产品的收购价格；三、人类活动对农业区位选择的影响农业的区位选择不是绝对的，便也是有一定限度的。1、自然因素的利用和改造人类活动对自然因素的影响（1）扩大农作物的区位范围培育良种、改良耕作制度等技术改革措施举例 我国天然橡胶的种植原只能种植热带，如我国海南岛和西双版纳有种植。而现在培育的良种天然橡胶已经可以生长到北纬 32 度的地区。双季稻的种植范围推广到江淮平原。小麦的种植高限扩展到海拔4000 米的高度（2）改造不利因素经济技术条件、投入产出比举例运用温室效应原理，改善作物生长的温度因素2、社会经济因素的发展变化人类活动对社会经济因素的影文档编码:CY6O9F8G2E10 HH3M10G3Y8H6 ZK9I10A1K6O1文档编码:CY6O9F8G2E10 HH3M10G3Y8H6

ZK9I10A1K6O1名师精编优秀教案承转虽然澳大利亚混合农业取得了很大成绩，但也存在着问题。学生读图及课文（大分水岭的雨影效应及东思考水西调图）思考：目前制约墨累-达令盆地混合农业发展的限制条件是什么？教师总结由于墨累-达令盆地位于大分水岭的西侧，属雨影区，因而降水稀少。为此，澳大利亚政府不遗余力地修建水利工程，进行东水西调，保证这里农牧业的繁荣发展。学生活动（1）完成地图册后面有关5.4 这一节的练习；（2）完成同步练习中有关5.4 这一节的练习。【作业设计】课后总结混合农业主要特点及经营有哪些优势？【教学反思】文档编码:CY6O9F8G2E10 HH3M10G3Y8H6 ZK9I10A1K6O1文档编码:CY6O9F8G2E10 HH3M10G3Y8H6 ZK9I10A1K6O1文档编码:CY6O9F8G2E10 HH3M10G3Y8H6
