NPP Grassland: Matador, Canada, 1968-1972, R1

This data set contains five ASCII files (.txt format). Three files contain productivity data for a mixed prairie at the Matador Field Station, Canada, and two files contain climate data. The 8-km2 Matador Field Station (50.70 N, -107.72 W, Elevation 676 m) is located approximately 47-km north of the city of Swift Current in southern Saskatchewan Province at the northern limit of the "mixed prairie" portion of the North American Great Plains. The study area is located on the bed of a former glacial lake.

One NPP file contains monthly measurements of above-ground standing live and dead biomass and litter made in "Section 16" by harvest methods during the growing season from March or April 1968 to October or November 1972. The second NPP file contains monthly measurements of root biomass made at different depths in "Section 16" during the growing season from April 1968 to July 1971. The third NPP file contains monthly above-ground biomass estimates for a secondary study area during the growing season from May 1970 to August 1972. The climate data are reported from two locations, one file from a weather station at Swift Current (1938-1990) and the other from a weather station at the Field Station during the study period (1968-1972).

The above- and below-ground net primary productivity (ANPP and BNPP, respectively) were calculated for "Section 16" only. ANPP (363 g/m2/yr) was sum of the increase in green biomass over the growing season, plus increase in dead biomass and litter. BNPP (600 g/m2/yr) was the increase in root biomass over the growing season.

本数据集包含五个 ASCII 格式的文本文件。其中三个文件记录了位于加拿大马塔多勒观测站（纬度 50.70 N，经度 -107.72 W，海拔 676 米）的混合草原生产力数据，其余两个文件则包含了气候数据。马塔多勒观测站占地 8 平方公里，位于加拿大萨斯喀彻温省西南部斯威特科文市以北约 47 公里处，是北美大平原“混合草原”部分的北部边界。研究区域位于一个古冰川湖的湖床上。

其中一份净初级生产力（NPP）文件记录了从 1968 年 3 月或 4 月至 1972 年 10 月或 11 月生长季节期间，在“第 16 区”通过收割方法进行的地上生物量（活和死）以及凋落物的月度测量数据。第二份 NPP 文件记录了从 1968 年 4 月至 1971 年 7 月生长季节期间，“第 16 区”不同深度的根系生物量的月度测量数据。第三份 NPP 文件记录了从 1970 年 5 月至 1972 年 8 月生长季节期间，次级研究区域地上生物量的月度估算数据。气候数据来自两个地点，一份来自斯威特科文气象站（1938-1990 年），另一份来自研究期间（1968-1972 年）观测站内的气象站。

仅对“第 16 区”进行了地上与地下净初级生产力（ANPP 和 BNPP）的计算。ANPP（每年每平方米 363 克）是生长季节内绿色生物量增加量、死亡生物量和凋落物增加量的总和。BNPP（每年每平方米 600 克）是生长季节内根系生物量的增加量。
