LAMOST-textit{K}2（Ltextit{K}2）项目于2015年启动，旨在收集textit{K}2活动中目标的低分辨率光谱，类似于LAMOST-textit{Kepler}项目。截至2018年底，LAMOST共观测到126块Ltextit{K}2板。在将LAMOST数据版本6（DR 6）的目录与textit{K}2批准的目标进行交叉匹配后，我们发现了84，012个对象的160，619个可用光谱，其中大多数已经被观察了不止一次。通过LAMOST恒星参数管道（LASP）从70，895个天体的129，974个光谱中导出有效温度，表面重力，金属丰度和径向速度。内部的不确定性估计为81 K，0.15 dex，0.09 dex和5 kms$^{-1}$，分别来自一个频谱的信噪比在$g$带（SNR$_g$）为10。这些估计数是根据多次访问的目标的结果得出的。外部的准确性进行了评估，通过比较的参数，在共同的目标与APOGEE和GAIA的调查，我们通常发现线性关系。最后的校准提供，结合外部和内部的不确定性的巨人和矮人，分别。我们可以预见，这些光谱数据将被广泛应用于不同的研究领域，特别是结合textit{K}2光度学。
The LAMOST-textit{K}2 (Ltextit{K}2) project, initiated in 2015, aims to collect low-resolution spectra of targets in the textit{K}2 campaigns, similar to LAMOST-textit{Kepler} project. By the end of 2018, a total of 126 Ltextit{K}2 plates had been observed by LAMOST. After cross-matching the catalog of the LAMOST data release 6 (DR6) with that of the textit{K}2 approved targets, we found 160,619 usable spectra of 84,012 objects, most of which had been observed more than once. The effective temperature, surface gravity, metallicity, and radial velocity from 129,974 spectra for 70,895 objects are derived through the LAMOST Stellar Parameter Pipeline (LASP). The internal uncertainties were estimated to be 81 K, 0.15 dex, 0.09 dex and 5 kms$^{-1}$, respectively, when derived from a spectrum with a signal-to-noise ratio in the $g$ band (SNR$_g$) of 10. These estimates are based on results for targets with multiple visits. The external accuracies were assessed by comparing the parameters of targets in common with the APOGEE and GAIA surveys, for which we generally found linear relationships. A final calibration is provided, combining external and internal uncertainties for giants and dwarfs, separately. We foresee that these spectroscopic data will be used widely in different research fields, especially in combination with textit{K}2 photometry.
