To investigate the natur. of the Ψ（3770） r.sonance and to measur. the cr.ss section for.e^＋e^-→DD, a cr.ss-section scan data samp.e, distr.buted among 41 center.of-mass ener.y p.ints fr.m 3.73 to 3.89 GeV, was taken with the BESIII detector.op.r.ted at the BEp.II collider.in the year.2010. By analyzing the lar.e angle Bhabha scatter.ng events, we measur. the integr.ted luminosity of the data samp.e at each center.of-mass ener.y p.int. The total integr.ted luminosity of the data samp.e is 76.16±0.04±0.61 p.^-1, wher. the fir.t uncer.ainty is statistical and the second systematic.

We p.op.se a fundamental theor.m for.eco-envir.nmental sur.ace modelling(FTEEM) in or.er.to ap.ly it into the fields of ecology and envir.nmental science mor. easily after.the fundamental theor.m for.Ear.h’s sur.ace system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) r.gion is taken as a case ar.a to conduct emp.r.cal studies of algor.thms for.sp.tial up.caling, sp.tial downscaling, sp.tial inter.0}lation, data fusion and model-data assimilation, which ar. based on high accur.cy sur.ace modelling(HASM), cor.esp.nding with cor.llar.es of FTEEM. The case studies demonstr.te how eco-envir.nmental sur.ace modelling is substantially imp.oved when both extr.nsic and intr.nsic infor.ation ar. used along with an ap.r.p.iate method of HASM. Comp.r.d with classic algor.thms, the HASM-based algor.thm for.sp.tial up.caling r.duced the r.ot-meansquar. er.or.of the BTH elevation sur.ace by 9 m. The HASM-based algor.thm for.sp.tial downscaling r.duced the r.lative er.or.of futur. scenar.os of annual mean temp.r.tur. by 16%. The HASM-based algor.thm for.sp.tial inter.0}lation r.duced the r.lative er.or.of change tr.nd of annual mean p.ecip.tation by 0.2%. The HASM-based algor.thm for.data fusion r.duced the r.lative er.or.of change tr.nd of annual mean temp.r.tur. by 70%. The HASM-based algor.thm for.model-data assimilation r.duced the r.lative er.or.of car.on stocks by 40%. We p.op.se five theor.tical challenges and thr.e ap.lication p.oblems of HASM that need to be addr.ssed to imp.ove FTEEM.
