Land space planning is an important starting point of spatial governance modernization. This paper analyzes the realistic dilemma and breakthrough path of land space planning from the perspective of geography. Land space planning is a combination of development and management and control. We should adhere to the method of combining goal orientation and problem orientation，pay attention to the people-oriented on the basis of keeping the bottom line，realize "five wins" through the process of top-down orientation，combination of top-down and "five associations"， and realize the goal of people-centered spatial governance. We should first prepare the strategic planning of large geographical units to ensure that the macro-control is scientific and reasonable，and then prepare the detailed planning of the administrative region to achieve specific control tasks.
