In this paper, we present the detailed analysis of recurrent homologous jetsoriginating from an emerging negative magnetic flux at the edge of an ActiveRegion. The observed jets show multi-thermal features. Their evolution showshigh consistence with the characteristic parameters of the emerging flux,suggesting that with more free magnetic energy, the eruptions tend to be moreviolent, frequent and blowout-like. The average temperature, average electronnumber density and axial speed are found to be similar for different jets,indicating that they should have been formed by plasmas from similar origins.Statistical analysis of the jets and their footpoint region conditions revealsa strong positive relationship between the footpoint-region total 131 {\AA}intensity enhancement and jets' length/width. Stronger linearly positiverelationships also exist between the total intensity enhancement/thermal energyof the footpoint regions and jets' mass/kinetic/thermal energy, with highercross-correlation coefficients. All the above results, together, confirm thedirect relationship between the magnetic reconnection and the jets, andvalidate the important role of magnetic reconnection in transporting largeamount of free magnetic energy into jets. It is also suggested that thereshould be more free energy released during the magnetic reconnection of blowoutthan of standard jet events.
