It will directly affect the regeneration level of forest resources and the diverse ecological value functions. In this article, the mainstream model paradigm of forest economics, that is, the basic framework of the Faustmann model and its evolution process are made in a more detailed explanation, especially the extended model including considered silvicultural effort, tax subsidies, risk dynamic management, and forest regeneration factors are made in more detailed explanations. This article concludes with the future further research directions of forest economics, including the design of dynamic models that includes considered uneven-aged forest management, non-timber goods and services, dynamic forest models. The research reflects the general trend of interdisciplinary and cross-border.展开更多

Assessment was done by means of multistage random sampling. The homestead sizes of the study area were classified into 3 groups viz, large （〉0.25 ha）, medium （0.05-0.25 ha） and small （〈0.05 ha） based on the result obtained from a preliminary survey, and a total of 45 homesteads, 15 from each group, were selected randomly for the study. The average annual income from homestead＇s plant diversity varied from Tk 5730.00 （US$95.5） to Tk 17500.00 （US$291.67）. The rural people were mainly dependent on their homegarden for woodfuel and nutritional requirement as forest was unavailable in the island. The rural people here also cultivated the plant species as a safety measure from frequent cyclone. Constraints hindering the development of homestead plantation were identified and suggestions were given such as the adequate supply of seedlings of fast growing native species and conservation of endangered species to meet the demand of the household as well as to keep ecological balance.展开更多
