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.

The article reviews the application of GIS technology to urban planning and the research progress on construction suitability evaluation. It points out that the present evaluation method invisibly weakens high eco-sensitivity areas and unsafe areas, and therefore the evaluation process can not objectively reflect the different angles of urban land use and its contradiction and unity. Thus, the article suggests strengthening the idea of giving priority to ecology and city safety through analyzing key sensitive factors and perfecting multi-factor superposition method. It explores a new idea for land suitability evaluation from three angles, that is, eco-sensitivity evaluation, construction suitability evaluation and city safety. An empirical study is conducted on the master planning of Hongya County Town.

<p><strong>[<em>Land Characteristics for Suitability of Apples</em> (<em>Malus sylvestris</em> Mill.) <em>in Sindang Dataran District, Rejang Lebong Regency, Bengkulu</em>]</strong></p><p><strong><br /></strong></p><p>Penilaian kesesuaian lahan merupakan tahap pertama dan penting dalam usaha pengembangan suatu komoditas pertanian. Kecamatan Sindang Dataran, Kabupaten Rejang Lebong merupakan salah satu lokasi yang direncanakan menjadi daerah pengembangan apel dengan temperatur udara mencapai 23oC dan ketinggian tempat bervariasi antara 785 – 1.129 lebih m dpl. dengan kondisi tanah yang cukup subur. Penelitian bertujuan untuk menentukan kelas kesesuaian lahan untuk tanaman apel. Penelitian dilakukan dengan metode survey dan observasi. Parameter yang diamati meliputi karakteristik lahan dan syarat tumbuh tanaman apel. Evaluasi kesesuaian lahan yang digunakan ialah kesesuaian lahan kualitatif, yaitu yang hanya didasarkan kondisi fisik lahan. Metode evaluasi kesesuaian lahan dilakukan dengan mengikuti prosedur dari FAO (1976), yaitu evaluasi kesesuaian lahan ini dilakukan dengan cara mencocokkan (matching) data antara karakteristik lahan dengan persyaratan tumbuh tanaman apel dan hasilnya didasarkan pada nilai terkecil (hukum minimum) sebagai keputusan kesesuaian lahan. Hasil penelitian menunjukkan bahwa kesesuaian lahan tanaman apel yang berada di Kecamatan Sindang Dataran, Kabupaten Rejang Lebong, dari faktor iklim termasuk S2 (cukup sesuai), sementara dari faktor ketersediaan hara termasuk S3 (sesuai marjinal). Hal yang menjadi faktor pembatas adalah rendahnya P tersedia, tetapi dapat diatasi dengan pemupukan sehingga dapat naik kelas menjadi S2. Melalui usaha pemupukan P maka Kecamatan Sindang Dataran memiliki potensi sebagai daerah pengembangan tanaman apel yang cukup sesuai.</p><p><strong>Keywords</strong></p><p>Karakteristik lahan; Kesesuaian lahan untuk tanaman apel; Malus sylvertris Mill</p><p><strong>Abstract</strong></p><p>Land suitability assessment is the first and important stage in the development of an agricultural commodity. Sindang Dataran District, Rejang Lebong Regency is one of the locations that is planned to be an apple development area with air temperatures reaching 23oC and altitude varying between 785–1,129 meters above sea level with fairly fertile soil conditions. The aim of the study was to determine the land suitability class for apple plants. The research was conducted using survey and observation methods. Parameters observed included land characteristics and growing conditions for apple plants. Land suitability evaluation used qualitative land suitability, which is only based on the physical condition of the land. The land suitability evaluation method is carried out by following the procedure from FAO (1976), namely the evaluation of land suitability is carried out by matching data between land characteristics and the requirements for growing apples and the results are based on the smallest value (minimum law) as a land suitability decision. The results showed that the suitability of the land for apple crops in Sindang Dataran District, Rejang Lebong Regency, from climatic factors including S2 (quite suitable), while from nutrient availability factors including S3 (marginal according to). The limiting factor is the low available P, but it can be overcome by fertilization so that it can be promoted to S2. Through P fertilization efforts, Sindang Dataran District has the potential as a suitable apple crop development area.</p>
