公共林带缺口与树冠状况普查（地坛公园） / Canopy gap and tree-condition survey of the public planting belt (Ditan Park, Beijing, CN).

地坛公园的公共林带哪几段有缺口、哪些树需要补水或补植，从来没有成表的记录，补植计划只能靠印象。 / Nobody has ever put the canopy gaps at Ditan Park into a table, so which sections are open and which trees need water or replacement is guesswork, and the replanting plan rests on impression.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

分段汇总表＋逐段定点照片＋缺口长度实测＋GPS / section summary table + fixed-point photo per section + measured gap lengths + GPS

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Steps

1. 沿林带按50米分段编号。 / Number the belt in 50 m sections along its length.
2. 逐段记录树种（尽量识别）、株数与缺口长度。 / Record species where identifiable, stem count and gap length per section.
3. 逐株判定冠层状况等级：良好、一般、衰弱。 / Grade each tree's crown condition: good, fair or declining.
4. 记录可补植空位数量与位置。 / Count and locate the vacant planting positions.
5. 每段拍摄一张定点照片并出具汇总表。 / Take one fixed-point photo per section and produce the summary table.

What counts as done

• 分段汇总表（树种、株数、状况等级） / Section summary table with species, count and condition grade
• 每段一张定点照片 / One fixed-point photo per section
• 缺口长度与可补植空位数 / Gap lengths and vacant planting positions counted
• 每段GPS坐标 / GPS waypoint per section

Proof is measured against these, not judged by taste.

The standard this serves

Urban Canopy. Urban canopy is the layer of leaves over a city, and it is infrastructure as surely as the pipes below the street: shade that cools a block in a heat wave, roots that drink a storm. The i-Tree protocol turns it into something you can count, tree by tree, so a city knows what it has and what it is losing. Mastery looks like a person who can read a whole street's trees at a walk. This packet is a piece of that census: a few trees observed carefully and recorded where the record counts.
