[Objective] This paper takes the case of Ostad Estate in southern Sweden as an example to make a 10 year medium term forest management planning of multi-objective of timber harvest and nature conservation according to the main requirements and implementations of Sweden. [Method]The process included sample survey, growth forecast by ProdMod, result analysis and planning make. The field investigation was implemented during October 2017 to December 2017. [Result]According to the panning, until 2027, there will be 15 sublots, 2 136.40 m~3 volume will be thinned, net income is 278 480.80 SEK; 33 sublots, 15 497.00 m~3 volume will be clear felled, net income is 1 481 695 838.0 SEK; 27 sublots, 45.39 ha need to be regenerated, the cost is 1 804 742.88 SEK; 9 sublots, 13.75 ha area young seedlings need pre-commercial thinning; 22.87 ha forest area will be added into nature conservation area. [Conclusion] At the end of 2027, 170.88 ha of area will be used for wood production, and 35.39 ha of forest area for ecological reserve, the total net income is 1.48 billion SEK in ten years, the net present value is 1.22 billion SEK. In this planning, the total harvest amount will be smaller than growth amount during the period, sustainable harvest target could be reached, the reasonable age distribution makes sure of the stable annual income, the enlarged ecological reserve area provides a good protection on flora and fauna. Basically, the plan achieves the dual goals of timber harvesting and nature reservation. However, potential risks include natural hazard, market situation as well as climate change would influence the result of management, the strategies are improving the income and altering species.
