1、首先确保你的Echarts已安装并引入。（可查看我的其他博客，里面有Echarts图表使用）
2、进入阿里云数据可视化平台下载（2）或在线获取地图json文件（1）。地址是：DataV.GeoAtlas地理小工具系列 (aliyun.com)
3、首先介绍下载地图的json文件的使用方法。（方法一）
在项目的src目录下新建一个文件夹或者放在你的静态文件目录下，在这里我是新建了一个json文件夹，将下载好的地图json文件放在里面。
4、使用Echarts引入地图（相关配置项已注释）。
<script setup lang="ts">
// 引入 Echarts、全国地图数据
import * as echarts from "echarts";
// 导入地图，方法一
import china from "../json/china.json";
import { ref, onMounted } from "vue";
const main3 = ref();
onMounted(() => {
chinaMap();
});
function chinaMap() {
// 初始化echarts
var myChart = echarts.init(main3.value);
// 解决china直接引用提示类型问题
const chinas: any = china;
// 使用地图并注册地图名称
echarts.registerMap("china", chinas);
let option = {
tooltip: {}, // 鼠标移到图里面的浮动提示框
series: [
{
// 类型是地图
type: "map",
map: "china",
// 设置geoIndex可解决地图重叠问题
geoIndex: 0,
},
],
// 这个是重点配置区,地理坐标系组件
geo: {
// 地图名称需与注册地图名称保持一致
show: true,
// 类型是地图
type: "map",
map: "china",
// regions: {},
// 默认样式
itemStyle: {
// 每个地图区块色
areaColor: "#91EBF7",
// 边框颜色
// borderColor: "#2AAAF8",
},
// 高亮状态下的多边形和标签样式。鼠标移入样式
emphasis: {
itemStyle: {
// 鼠标滑过高亮区块颜色
areaColor: "#C491F7",
},
// 鼠标滑过高亮文字颜色
label: {
color: "white",
},
// 聚焦时淡出其他区块
// focus: "self",
},
// 标签
label: {
// 是否显示标签
show: true,
// 文字样式
// 每一个省份标签文字色
color: "rgba(246, 91, 39, 0.5)",
},
zoom: 1.2, // 地图放大
aspectScale: 0.8, //地图宽高比例
roam: true, //地图缩放、平移
// 滚轮缩放的极限控制
scaleLimit: {
min: 0.5, //缩放最小大小
max: 6, //缩放最大大小
},
},
};
myChart.setOption(option);
}
</script>5、注意：这里因为在阿里可视化平台下载的json文件运行起来的省份名称是全称（后续如果有好的办法可以解决的话我会更新），所以我使用的是自己新建的json文件。内容如下：

6、 方法二：在线引用地图json文件。首先在src目录下新建一个api文件夹，里面新建一个.ts文件，代码如下：
import axios from 'axios'
export default axios.get('https://geo.datav.aliyun.com/areas_v3/bound/100000_full.json')
// 获取全国地图数据(方法二通过在线请求)7、在组件中发请求获取json文件并使用Echarts引入地图（相关配置项已注释）。
<script setup lang="ts">
// 引入 Echarts、全国地图数据
import * as echarts from "echarts";
import getMap from "../api/getMap";方法二
import { ref, onMounted } from "vue";
const main3 = ref();
onMounted(() => {
chinaMap();
});
function chinaMap() {
// 初始化echarts
var myChart = echarts.init(main3.value);
// 解决china直接引用提示类型问题
const chinas: any = china;
myChart.setOption(option);
// 显示 loading 动画
myChart.showLoading();
// 再得到数据的基础上，进行地图绘制（方法二在线请求）
getMap.then((res) => {
// 得到结果后，关闭动画
myChart.hideLoading();
// 注册地图(数据放在axios返回对象的data中哦)
echarts.registerMap("china", res.data);
let option = {
tooltip: {}, // 鼠标移到图里面的浮动提示框
series: [
{
// 类型是地图
type: "map",
map: "china",
// 设置geoIndex可解决地图重叠问题
geoIndex: 0,
},
],
// 这个是重点配置区,地理坐标系组件
geo: {
// 地图名称需与注册地图名称保持一致
show: true,
// 类型是地图
type: "map",
map: "china",
// regions: {},

},

},
};
myChart.setOption(option);
});
}
