[Evaluation of sustainable utilization of fishery resources in Guangdong Province].
Sustainable utilization of fishery resources is the key for the sustainable development of fisheries, and its evaluation is a critical topic in the management of fisheries. Based on the theories of sustainable utilization, an index system suitable for the evaluation of the sustainable utilization of fishery resources in Guangdong Province was established, and a hierarchy and comprehensive grey evaluation model was adopted to evaluate this sustainable utilization in 1978-2007. In the study period, the utilization level of fishery resources in this province had an overall decrease, being the lowest in 1998, only 37.3% of that in 1978; but in the nearest 10 years, this utilization level had an increasing trend, with that in 2007 being 55.1% of 1978. The results of comprehensive evaluation were consistent with the observed facts, indicating that the model was feasible to evaluate the sustainable utilization of regional fishery resources.
