Different from the solution/physical pump, biological pump and continental shelf pump of carbon cycle in oceans, a new pump named “surface microlayer (SML) pump” is developed based on data obtained from marine investigations and lab study. The SML pump has: (1) left-right dissymmetry of “pH-depth” curve; (2) the non-linearity of “concentration-depth” curve; and (3) difference of affect-ing confine of the SML pump. The issue of “source” or “sink” of atmospheric CO2 in the Yellow Sea and South China Sea is discussed. 展开更多

农业税、"三提五统"的存在既影响了农民对农地物权属性的认识、土地承包经营制的推行以及土地承包经营权的建设,也导致了集体地权与农民地权之间的冲突,并间接导致农民个人地权之间的冲突。农业税、"三提五统"的废... 农业税、"三提五统"的存在既影响了农民对农地物权属性的认识、土地承包经营制的推行以及土地承包经营权的建设,也导致了集体地权与农民地权之间的冲突,并间接导致农民个人地权之间的冲突。农业税、"三提五统"的废除使得农地物权的私法属性得以彻底显现,为农地物权的完善与良性运作创造了条件。 展开更多
关键词 农业税 “三提五统” 集体土地所有权 土地承包经营权
