調查成果與清單：非常常用的是非常新的森林資源規劃設計調查（二類(lèi)調查）成果，包括調查報告、小班卡片（或小班因子一覽表）、林相圖、森林分布圖等。

Survey results and inventory: The most commonly used are the results of the latest forest resource planning and design survey (Type II survey), including survey reports, sub-compartment cards (or sub-compartment factor checklists), forest phase maps, forest distribution maps, etc.

Special survey data:

如果是即將采伐的林分，需提供伐區調查設計資料及審批手續。

If the forest stand is to be logged soon, it is necessary to provide the survey and design data of the logging area as well as the approval procedures.

如果是新造林地或有近期營(yíng)林活動(dòng)，需提供作業(yè)設計調查及驗收材料。

If it is a newly planted forest land or there have been recent silvicultural activities, it is necessary to provide operation design survey and acceptance materials.

如果是經(jīng)濟林、竹林或苗圃，需提供品種、樹(shù)齡、生長(cháng)狀況、年產(chǎn)量、苗木規格與數量等專(zhuān)項資料。

If it is an economic forest, bamboo forest, or nursery, special information such as variety, tree age, growth status, annual yield, and seedling specifications and quantity needs to be provided.

圖面資料：包括林場(chǎng)小班地形圖（通常比例尺為1:10000或1:25000）、山林權權屬圖等。

Graphic materials: including topographic maps of forest farm sub-compartments (usually with a scale of 1:10000 or 1:25000), forest ownership maps, etc.
