As the most important natural resource, sustainable use of land resource is the essential guarantee of sustainable development. The nature of sustainable use of land resource is to retain the quantity and productivity of land resource from generation to generation.The evaluation of sustainable use of land resource is an important method to ensure land use to get onto the sustainable track. Furthermore, building index system is the key of the evaluation. In view of tendency of the evaluation indexes chosen so widely, the evaluation indexes should include only three kinds in the researches on the evaluation of sustainable use of land resource. The first is the stock and structure index of land resource, viz. Areas quantity structure of land resources. In China, it is especially paid attention to the per person index of land quantity and rate between cultivated land and farmland. The second is the productive index of land, which includes the productivity, potentiality, stability and renewal situation of land. The third is the sustained index of land environment. On the evaluation research of area level, we should lay particular emphasis on statistic indexes. With a case of Guangxi Zhuang Autonomous Region in China, the evaluation index system of sustainable land use in county area has been built in this thesis. Using the weighted average method to calculate the means of sustainable land use in each county, according to the land using situation, all counties in the autonomous region have been divided into three types. (1) Sustainable Pattern contains 18 counties, which have higher land resource productivity, stronger sustained abilities of land environment .The economic benefits of land using in these counties are obviously higher. These counties have gotten highly intensive farming, and they are all in the good circumstance. (2) Basically Sustained Pattern contains 48 counties, which productivity of land resource is of middle level. In part of counties and cities, the stock of land resource inclines to lower level, but their land using potentialities are still greater. Through changing land using pattern, these counties can rapidly enter in a good circumstance. (3) Critically Sustained Pattern contains 14 counties, which are mostly in the karst mountain areas. They have less stock of land resource, lower productivity and more extensive cultivation. The productivity of land renewing has been hindered, so it urgently need to be renovated. At last, the writers have explored the basic ways of sustainable use of land resource in Guangxi, China — (1) Retain the stock of land resource and strictly manage farmland uses. (2) Strengthen the value accounting of land resource, and control the farmland occupation of non agricultural construction. (3) Depend on technology advanced, optimize the land using structure, and promote the productive level. (4) Carry out land management all round, and improve the ecological environment of land resource. (5) Enhance evaluation researche and land monitoring, and promote the sustainable utilization level of land resource.展开更多

Mining sector is a strategic sector in East Kalimantan but post coal mining land has the problem for land using. The research method used survey method and laboratory test on 21 entities/companies with the status of cooperative and non-cooperative approach and land resource evaluation on 30 respondent keys （key informant）. Analysis of data is using the evaluation of land potential： Analytical Hierarchy Process （AHP）, IRR, NPV and BCR. The results showed that there are 2 scenarios decisions in the development of coal mining region that is the optimistic scenario on 2 aspects namely： （1） tourism （recreational parks and historical tours） and （2） aspects of the fishery （tilapia, goldfish, catfish）. Then, in the moderate scenario, there are 3 aspects of development： （1） services （administration and housing）; （2） fisheries （cork fish and damselfish） and （3） agriculture （guava, melinjo and dragon fruit）. Optimizing the utilization of post-coal mining land in the regency of Kutai Kartanegara can be carried out with reference to these two types of scenarios as a manifestation of an engine of regional development.展开更多
