Taking Guangxi agriculture and cultivation state-owned Jinguang Farm, Qianjiang Farm, Xinxing Farm and Liangqi Farm as land reclamation cases studies, 16 evaluation indices were selected from four aspects, i.e., investment in land reclamation project, implementation intensity of land reclamation, land use structure, and efficiency output of land reclamation, to evaluate the reasonability of land reclamation in the project area. The improved TOPSIS method and obstacle degree model were used to evaluate reasonability and diagnose obstacle factors. Results showed that the efficiency output of land reclamation had the greatest impact on its reasonability, followed by land use structure, with investment of land reclamation project having the least impact. The index obstacle factors mainly referred to the improved value of land quality. Through analysis of the evaluation results, the reasonability and obstacle factors of land reclamation were objectively determined to provide a reference for land reclamation in practice.

Between 1950 and 1956, one fifth of the Italian landscape was profoundly reshaped. According to the first ten-year plan issued by the Cassa per il Mezzogiorno, 51 aqueducts and around 3,000 km of roads would provide the necessary infrastructure to rehouse millions of farmers, while 139 new settlements and 46,450 isolated houses would result from the new subdivision of land. Besides the national funds, newly established local authorities were entrusted with the handling of all technical aspects concerning land reclamation and resettlement. Far from being the mere result of political agreements, such an impressive and multi-faceted reform process stood at the intersection of cultural debates, national ambitions and foreign ascendancies that sought substantial alternatives to modernization and urbanization. This paper highlights an off-radar case study, with the aim of presenting and understanding some of the aspects featuring in the Italian discourse on rural planning. It deals with the intervention of the Bradano Valley Land Reclamation Authority and its main consultant, Nallo Mazzocchi Alemanni, and frames their efforts in the larger and multifaceted postwar Lucanian experience. Inscribed in the contemporary debate on regionalism and planning, the technical stance of Mazzocchi Alemanni would provide the foundation upon which to unfold the interweaving of contradictory ideologies deployed by intellectuals and activists seeking to uplift the Italian Mezzogiorno.

Land is the most important means of production in agriculture. Valuation of agricultural land resources takes into account the acreage and land quality. Changes in the land use structure are stimulated by many factors. It ought to be remembered that the farmland also provide space for purposes other than agriculture or forestry. The paper presents those changes in the land use structure in Poland which took place in the period of 2002–2010. On the basis of the data by the Central Statistical Office [GUS] and its Agricultural Censuses of 2002 and 2010 the authors propose an agricultural holding territorial importance indicator, land location indicator, change indicator for agricultural land turned into non-agricultural land and analyse the total area of agricultural holdings. The major determinants (internal and external factors) of those changes are also described. The aim of the study is to analyse the changes taking place in the Polish agriculture. They were taken into account natural, ecological and urban determinants as well as to the Common Agricultural Policy. The analyses were conducted at the level of voivodships and poviats and were contained agriculture land and non-agriculture land. The area of agricultural land is decreasing as it is being dedicated for other – non-agricultural – purposes, especially for housing purposes.

Land use structure optimization is the core of land use planning, which has significant influence to the carbon cycle in terrestrial ecosystems. In this paper, we put Lanzhou as case study, to realize the land ecosystem carbon balance is the breakthrough point, using the method of fuzzy linear programming, constructing model from carbon source and carbon sink, trying to put forward a new approach to optimize the land use structure. Contrast with the former planning with the optimization scheme based on carbon balance, carbon stock volume and carbon emissions of the year 2005 and 2020 are evaluated .We got a low carbon optimization scheme of land use planning finally. The results of the study show that the objective to make carbon storage maximization and to make carbon emissions minimization is consistent and the two optimizing schemes have dramatically beneficial effect on increase carbon sink and reduce carbon source, which can slow down carbon emissions in terrestrial ecosystems and realize the rational utilization of land resources and the sustainable development.

In order to research the effect of land reclamation on landscape ecological quality(LEQ) in mining area, taking Jiawang mining area in Xuzhou as an example, LEQ and its changes before and after reclamation were evaluated with an indices system which was constructed form stability and interference level of landscape ecosystem based on RS, GIS and landscape ecology. The weight was assigned for each index by analytical hierarchy process (AHP) and entropy technology. The results showed that land use of the study area dramatically changed, manifesting by farmland continuous decreases and the built-up areas rapid increases, secondly, woodland decreases after increasing, grassland and water slight increases, which were in an unbalanced state overall. The landscape ecological situation of the study area had a better trend from 2001 to 2010, implying that land reclamation project had played a certain improvement on the regional ecological environment in mining area. It is believed that this work may provide scientific reference for land reclamation and landscape restoration of coal mining area.
