Investigation and Assessment of Land Utilization Condition in a Small Watershed of the Upper Reaches of Pearl River
the land utilization condition before and after compre-hensive management in the Jianshanhe small watershed is investigated
and its land quality is assessed using the comprehensive index method and AHP. The result from the investigation shows that the areas of forest-land
shrub land
fruit land
and terrace land are increased by 423.5
299.9
17.6 and 32.0 hm2
respective-ly. The areas of new open forestland
sloping farmland
and bare land are decreased by 487.4
164.3 and 164.5 hm2
respectively. Conservation land and economic forest land are two new land types. Irrigated land
water-land
unutilized land and difficultly utilized land are balanced.The result of assessment indicates that the 3rd and 4th grade lands account for 67.20% of the whole area before restoration
while the 2nd and 3rd grade lands account for 71.37% of the whole area after comprehensive management. In one word
