Growth Requirement

Food cultivation, especially upland rice is needed to fulfill the needs of dryland food. It is necessary to evaluate the suitability of the land so that it can overcome land constraints to increase the productivity of upland rice in Tirtomoyo Regency. The unit of analysis is Soil Mapping Unit based on soil type map using ArcGIS 10.1 and determination of sample point based on purposive sampling method. Data analysis was done by matching between the result of soil characteristic which has been obtained with growth requirement of the upland rice. Based on the results, District Tirtomoyo divided into 4 Soil Mapping Unit. The actual land suitability class for upland rice is moderately suitable (S2) and not suitable (N). Limiting factors include rainfall, slope, erosion hazard, basic saturation, CEC, C-organic, N-total, K<sub>2</sub>O. Improvement efforts are done by arranging cropping pattern, drainage management, a making of terracing, cover crop planting, implementing organic material, and fertilizing. The suitability class of potential land of upland rice is highly suitable (S1) and marginally suitable (S3).

User Friendly

Agricultural land use planning should always be guided by a reliable tool to ensure effective decision making in the allocation of land use and activities. The primary aim of this study is to develop a user friendly system on a spatial basis for agricultural land suitability evaluation of four groups of agriculture commodities, including food crops, horticultural crops, perennial (plantation) crops, grazing, and tambak (fish ponds) to guide land use planning. The procedure used is as follows: (i) conducting soil survey based on generated land mapping units; (ii) developing soil database in GIS; and (iii) designing a user friendly system. The data bases of the study were derived from satellite imagery, digital topographic map, soil characteristics at reconnaissance scale, as well as climate data. Land suitability evaluation in this study uses the FAO method. The study produces a spatial based decision support tool called SUFIG-Wilkom that can give decision makers sets of information interactively for land use allocation purposes.This user friendly system is also amenable to various operations in a vector GIS, so that the system may accommodate possible additional assessment of other land use types.

Land Suitability Evaluation

Constructive land suitability evaluation is the premise of effectively disposing land resource. China is in the historical period that urbanization develops fleetly; the demand of construction land grows rapidly; carrying on the research about method of constructive land suitability evaluation presents strong practical significance and broad application prospect. The paper summarizes basic analysis method of constructive land suitability evaluation based on GIS from five basic links which cohere each other, and then introduces the research development of constructive land suitability evaluation from angles of ensuring evaluation factor and factor weight, evaluation factor classification, land classification. Finally, the paper analyses research direction of this work from angles of consummating the evaluation method and using new mathematical method, releasing the related criteria by government department, and the combination between urban extended model, area development strategy, and GIS.
