搜狗地图标注

We need to write article content, 1500+ characters, 6-8 paragraphs each 150-250 characters? Actually says each paragraph 150-250字 (Chinese characters). Must be 6-8 paragraphs, each 150-250 characters. Ensure total >=1500 characters, <1050 not allowed. So we need at least 6 paragraphs of 250 characters = 1500 characters. Or 7 paragraphs of 250 = 1750. Let's aim for 7 paragraphs each ~230 characters = ~1610 characters. Must be Chinese natural style, no AI words, no banned words. Must not include title. Title already given, we just output body.

Need to avoid AI listing words, avoid formal phrases. Use short sentences, active voice, specifics. No "" etc.

Paragraph structure: start with hook referencing title? They said "开头呼应标题引入话题". So first paragraph should reference title concept. Then later conclusion should echo title.

Let's craft 7 paragraphs each ~230 Chinese characters.

We must count characters. Let's draft paragraphs.

Paragraph 1: hook, talk about map legend annotation as key to reading space. ~230 characters.

Paragraph 2: talk about symbols and colors, examples.

Paragraph 3: talk about hierarchy of symbols, how to interpret.

Paragraph 4: talk about scale and north arrow, relation.

Paragraph 5: talk about real-world case, like city planning.

Paragraph 6: talk about common mistakes, how to avoid.

Paragraph 7: concluding, echo title, insight.

Now need to count characters. Let's draft with approximate count.

I'll write each paragraph and then count characters manually? Approx.

"地图的图例和标注，其实是一把打开空间信息的钥匙。每次抬头看地图，总会看到那一串色块和符号，它们像语言的字母表，却不需要背熟，只要懂规则就能读懂。"

Count characters (including punctuation? Chinese characters count). Let's count:

地(1)图2的3图4例5和6标7注8，9实10际11是12一13把14打15开16空17间18信19息20的21钥22匙23。24每25次26抬27头28看29地30图31，32总33会34看35到36那37一38串39色40块41和42符43号44，45它们46像47语48言49的50字51母52表53，54却55不56需57要58背59熟，60只61要62懂63规64则65就66能67读68懂69。70

So 70 characters, too short. Need 150-250 characters. Need to expand.

Add more: "它们在城市规划、环境监测、旅行导航里发挥作用，背后藏着大量的空间数据。" Let's count added.

它们1在2城3市4规5划6、7环8境9监10测11、12旅13行14导15航16里17发18挥19作20用21，22背23后24藏25着26大27量28的29空30间31数32据33。34

So total now 70+34=104. Still short. Need 150-250. Add more: "比如，一张环境噪声分布图，颜色从浅到深代表声音强度，读图者可以直接看到繁华街区的噪声热点。" Count characters.

比如，1一2张3环4境5噪6声7分8布9图10，11颜12色13从14浅15到16深17代18表19声20音21强22度23，24读25图26者27可28以29直30接31看32到33繁34华35街36区37的38噪39声40热41点42。43

Add 43 characters. Total 104+43=147. Need at least 150. Add a few more characters: "这正是图例和标注的威力所在。" Count.

这1是2正3确4图5例6和7标8注9的10威11力12所13在14。15

Add 15 => total 162. Good within 150-250.

Paragraph 1 ~162 characters.

Paragraph 2: talk about symbols and colors, examples.

"地图上的符号千姿百态，从简洁的点、线到复杂的图形，每一种都有特定含义。比如，红色的圆点常代表行政中心，蓝色的波浪线可能标示河流，黄色的方块则指示商业区。颜色的选择也暗藏信息，暖色调往往用于提醒或强调，冷色调则用于描述背景。"

地1图2上3的4符5号6千7姿8百9态10，11从12简13洁14的15点16、17线18到19复20杂21的22图23形24，25每26种27都28有29特30定31含32义33。34例35如36，37红38色39的40圆41点41? Wait recount properly.

Let's write with punctuation: "地图上的符号千姿百态，从简%E
