摘要: Abstract Forestry is expanding in New Zealand and increasingly contributing to the economy. The expansion has also altered landscape will continue do so. In addition, implementation of district plan under Resource Management Act (RMA) 1991 directly influences forestry future land-use. Using Nelson region as a case study, difference land-use distribution patterns between mid-1970s 1990s, changes over 20 years were interpreted. factors influencing examined. Because mainly changed by human activity, change was considered from an economic perspective. Thus, productivity, capability (LUC), distance city center well physical attributes land. objective establish data set which could be predicted. Forest period shrub or pasture, horticulture pasture.
