Derived from the current score.
Contribution groups assessed so far; coverage is still being expanded.
ASSESSMENT SCOPEWhat this score covers
All included contribution titles and notes are available in English. The complete original text remains available in Chinese; both editions use the same scores and source links.
Uncovered contributions and unresolved harms are not treated as zero. This is not a complete assessment of a lifetime.
3 included contributions have incomplete evidence; the relevant gap appears with that contribution.
Original scope note
This research record currently includes 3 outcomes within a limited scope; M and attribution shares are revisable judgments. Uncovered content and negative effects not yet clarified are not treated as zero; specific gaps appear in the item-by-item explanations.
Original Chinese scope
本轮当前已列3项有限研究账；M与归功份额为可修订判断。未覆盖内容和未核清的负面作用不按零处理，具体缺口见逐项说明。
CALCULATIONHow the score is calculated
Q = 10^(M/2) − 1; Lᵢ = aᵢ × Qᵢ; L = Σ Lᵢ; S = 2 × log₁₀(1 + L).
M is an outcome’s assessed magnitude and a is the person’s allocated share. A standalone score is only a per-item reference; the attributed light from distinct contributions is what can be combined.
SCORE DETAILS
3 evaluated contributions
M is the assessed magnitude of an outcome; attribution is the person’s share of credit. Attributed light can be added. The standalone score is only a per-item reference and must not be added across rows.

01A research method using natural vegetation as an indicator of land and soil capacity自然植被作为土地与土壤能力指示的研究方法OUT-SL3478-1911-1940-VEGETATION-AS-LAND-AND-SOIL-INDICATOR
Record year1911
summaryA research method using natural vegetation as an indicator of land and soil capacity. The work's identity rests on joining USDA in 1908 and on land-capacity research in 1911.
Original Chinese · summary
自然植被作为土地与土壤能力指示的研究方法。1908加入USDA及1911土地能力研究的作品身份。
M rationaleUniversity of Arizona holdings confirm the 1911 work, and the USFS bibliography lists the 1911 work, the 1924/1940 works with Piemeisel, and the 1938 research; M5.5 is assigned for a sustained family of land-indicator methods.
Original Chinese · M rationale
亚利桑那大学馆藏确认1911著作，USFS文献目录列出1911、与Piemeisel的1924/1940及1938研究；按持续的土地指示方法族取M5.5。
attribution rationaleShantz receives 0.40, the USDA survey team 0.18, collaborators such as Piemeisel 0.08, prior work 0.19, USDA 0.07, and unresolved contributions 0.08.

overlap boundaryThe same family of methods encompassing the 1911 Great Plains study and related vegetation–soil indicator work of 1924/1938/1940; it counts research using natural vegetation to assist judgments about land/soil conditions, and is not credited with all agricultural planning, yields, or subsequent land policy.

1911大平原研究及1924/1938/1940相关植被—土壤指示工作的同一方法族；计以自然植被辅助判断土地/土壤条件的研究，不领取全部农业规划、产量或后世土地政策。
Evidence gapsThe data, classification rules, and forecast errors in the 1911 bulletin have not yet been checked chapter by chapter. Whether and how local farming, pastoral, and Indigenous knowledge entered the surveys, and how it should be credited, remain unresolved.

summaryFixed-point repeat photography and comparison of vegetation change across decades. Boundaries among the original-photo period, Shantz's repeat photography, and Phillips's subsequent delivery.
Original Chinese · summary
跨数十年定点复拍与植被变化比较。原片时段、Shantz复拍和Phillips后续交付边界。
M rationaleUSDA documentation identifies Shantz's 1958 repeat photography and Phillips's subsequent work; a Persée review records the 1958 Shantz/Turner report, 1309 old photographs, and 241 relocated sites. M5.7 is assigned for an independent long-term comparative outcome.
Original Chinese · M rationale

overlap boundaryThe cross-temporal comparison method and paired images formed by fixed-point repeat photography in Africa in 1956–1958 and in the northern Great Plains in 1958–1960; original 1919/1924 photographs and photographs after 1908 serve only as baselines and their collection value is not counted again, while the 1963 book is credited to Phillips and others as a subsequent delivery.

Evidence gapsThe sampling rules for repeat-photography locations, failed relocations, and image calibration have not been checked. Local assistance, Turner's analysis, and Shantz's photography have not been assigned specific divisions of labor because the original report has not been read.
