描绘新农村的蓝图——国家测绘局新农村建设测绘保障服务工作纪事

统筹规划 政策引领 新农村建设,需要有统一的科学规划。全面系统的整体规划和科学具体的建设规划,测绘部门就是编制这些规划底图的提供者,如在精细农业规划,村庄路网规划改造,卫生设施与环境规划,农户宅基地和承包土地规划与定界,集约用地规划,防灾减灾等方面,都需要及时,准确,经济的测绘服务与保障,需要权威的,现势性好的地理信息成果作为各项建设工作的统一平台和依据。

Study on Recovering the Earth＇s Potential Field Based on GOCE Gradiometry

Given the second radial derivative Vrr（P） ｜δs of the Earth＇s gravitational potential V（P） on the surface δS corresponding to the satellite altitude, by using the fictitious compress recovery method, a fictitious regular harmonic field rrVrr（P）^＊ and a fictitious second radial gradient field V：（P） in the domain outside an inner sphere Ki can be determined, which coincides with the real field V（P） in the domain outside the Earth. Vrr^＊（P）could be further expressed as a uniformly convergent expansion series in the domain outside the inner sphere, because rrV（P）^＊ could be expressed as a uniformly convergent spherical harmonic expansion series due to its regularity and harmony in that domain. In another aspect, the fictitious field V^＊（P） defined in the domain outside the inner sphere, which coincides with the real field V（P） in the domain outside the Earth, could be also expressed as a spherical harmonic expansion series. Then, the harmonic coefficients contained in the series expressing V^＊（P） can be determined, and consequently the real field V（P） is recovered. Preliminary simulation calculations show that the second radial gradient field Vrr（P） could be recovered based only on the second radial derivative V（P）｜δs given on the satellite boundary. Concerning the final recovery of the potential field V（P） based only on the boundary value Vrr （P）｜δs, the simulation tests are still in process.
