Annual runoff increases from thinning in Salt-Verde watersheds.

a ‘Scenario Name’ indicates number of years simulated in each scenario (15, 25, 35 years) and extent of forest thinned (low = 30% of forest thinned; mid = 45%; high = 60%). ‘Total Hectares’ are total number of hectares thinned in each scenario. ‘Hectares per Year’ are number of hectares thinned every year for 10 consecutive years (15-year scenarios), 20 consecutive years (25-year scenarios), and 30 consecutive years (35-year scenarios). ‘Effective Hectares per Year’ are the average number of thinned hectares across all years of the scenario that contribute to additional runoff (see figure 6).Estimates of additional runoff associated with thinning of ponderosa pine forests across Salt-Verde watersheds accounting for variation in treatment periods, total forest extent treated, and drought and pluvial periods of winter precipitation (Oct-Apr). Estimates rounded off to three significant digits.Annual runoff increases from thinning in Salt-Verde watersheds.情景名称（Scenario Name）用于表征各模拟情景的时长（15年、25年、35年）与森林疏伐强度：低强度疏伐指30%的森林被疏伐，中强度为45%，高强度为60%。总疏伐公顷数（Total Hectares）指各情景中累计被疏伐的森林总面积。年均疏伐公顷数（Hectares per Year）指对应情景下每年的平均疏伐面积：15年情景对应连续10年的年均疏伐量，25年情景对应连续20年，35年情景对应连续30年。有效年均疏伐公顷数（Effective Hectares per Year）指情景周期内所有年份中，可贡献额外径流的疏伐公顷面积的年均值（详见图6）。本数据集针对索尔特-佛得角流域（Salt-Verde watersheds）内黄松森林（ponderosa pine forests）疏伐所引发的额外径流进行估算，综合考量了疏伐处理周期、总疏伐森林面积，以及冬季降水（10月至次年4月）的干旱期与多雨期的变化差异。所有估算结果均保留三位有效数字。索尔特-佛得角流域的森林疏伐可带来年径流量的提升。
