摘要: Abstract We investigate the characteristics of an optimally managed spatially explicit renewable resource system. The bioeconomic system is depicted with a metapopulation model where subpopulations are connected by dispersal processes and affected spatial distribution harvesting effort. characterize optimal way to distribute effort over space time in order optimize returns from this spatial/dynamic also how allocation effort, harvesting, biomass compare second-best allocations that ignore find instruments reflect interplay between gradient rents biological dispersal. Using simple parameterization explore qualitative properties several specific examples, we solutions blend or average results differentiated case differ intuitive ways first-best optima.
