The application of Remote Sensing and GIS for Phu Rua National Park Zoning, Loei Province, Thiland
Initially weighing was design be obtained from questions districted t exerts and people concerned such as foresters envirnmentsits soil scientists and people concerned such as foresters, environmentalists, soil scientists and tourists. But the weighting score of the ordinal significant scale varied too much, because of the different knowledge a background of the respondents. This study used scores received only from forests. The scores are shown in
Table 3. from this table it was found that slope, water, and accessibility are significant factors of an Intensive Use Zone. Slope, accessibility, and wildlife habitat are important for an outdoor recreation zone. Vegetation type and wildlife habitat are significant factors of a primitive zone, a strict nature Reserve Zone and a recovery zone. Soil is important for a Recovery zone for considering erosive and suitability.
According to ranks and weights the formula of the zoning model can be express follows:
| IUZ : |
6.2rl+6.1r2+6,7r4+7.5r6+9.7r7+5r8 |
| ORZ : |
7.7 r1 +7r2+6r3+3+8.2r4+6,9r5+7,5r6+8,2r7+8r8 |
| PZ : |
8.7r1+4.2r2+4r3+5,2r4+4.2r5+4,1r6+2.6r7+8.1r8 |
| SNRZ : |
8.2r1+4.542+3.7r3+4.7r4+4.2r5+3r6+2.1r7+9.6r8 |
| RZ : |
8.5r1+5.5r2+7r3+4.5r4+4r5+5.7r6+4.6r7+8.1r8 |
where r1, r2, r3, r4, r5, r6, r7, and r8 are the ranking score of the value of each charcteristics as presented in
Table 2. respectively.
The third stage of the process was identification of suitability mapping for each zone. The ranks, weights and zoning models were written to perform the calculation of 8 variables by the defining look up table. The result of this stage was a suitability map for each of the zones, showing areas varying from suitable, moderate to not suitable. In the end these images were superimposed in order to get the final suggestion for management zoning . The criteria to revise the five preliminary zone boundaries consist of zone suitability class, and zone priority. If zones have the same suitable class, the priority is ranked from SNRZ, ORZ, PZ, IUZ, and RZ according to park goals and objectives that want to protect rare species, to provide outdoor recreation opportunities as well as to preserve water recharge area.
The existing facilities and outdoor recreation sites added directly to determine the suitability class of the Intensive Use Zone and suitability class of an Recreation zone respectively.
Results
- Obtaining the five management Zones
The results of the four stages mentioned above are 5 management zone maps. All maps have three suitability classes of suitable, moderate and not suitable. The suitability scores were grouped into 3 classes: low , medium and high suitability. These data are used as guild lines and suggestions about where and activity will be located For example when the park officers want to enlarge the recreation area, they would consider the area of high suitability for this class as the first priority.
- Final management Mapping
The final management zone
map is made by considering suitability class, and zone The results of
the face management zones and final map will be discussed during presentation.
