<p>The construction of the residential and commercial area of Pantai Indah Kapuk (PIK) 2 Cluster “D” is located in the part of two sub-district, which is Sub-district of Kosambi and Sub-district of Teluknaga. PIK 2 Cluster “D” has an area of 508,59 Ha. With the construction of PIK 2 Cluster “D”, there will be a change of land use and an enchancement of run off water. The relationship between the change of land use and the enhancement of run off water can be seen from run off peak deviation for reset time T year (Q<sub>r</sub>) on existing condition with planning condition after the change of land use. The method used is the rational method which is estimating run off peak. There is an enhancement off run off coefficient value (C) on existing condition about 0,46 and 0,81 on planning condition which causing an enhancement off run off peak in planning area as the effect of the change of land use as Q = 87,59 m<sup>3</sup>/second. The enhancement of run off coefficient value as the effect of the change of land use is directly proportional with the enhancement of run off peak in case study residential and commercial area of PIK 2 Cluster “D”.</p>

The development of tourism leads to changes in land-use demands and patterns, which are complex and dynamic, in tourist cities. Functional differences in land use produce different travel needs and have different impacts on traffic, especially on tourism. This paper explores the relationship between tourism land use and tourism traffic. Taking Xiamen Island as an example, using multivariable linear regression models, tourism land use is divided into accommodation land use, shopping land use and restaurant land use as the independent variables of the model; and the origin-destination (OD) density of traffic analysis zones (TAZs) during National Day in 2018 (October 1 to 5) is chosen as the dependent variable. To compare the different impacts between tourism land use and tourism traffic during the tourism and non-tourism periods, the non-tourism period (March 11 to 15) is further studied. The results show the following: (1) Xiamen, as a tourism city, has not only regular traffic but also tourism traffic, and traffic during the tourism period is totally different than that in the non-tourism period. (2) Tourism land use has a considerable impact on both tourism traffic and non-tourism traffic, but the impact is greater during the tourism period than the non-tourism period. (3) In the morning peak hour of both the tourism period and the non-tourism period, accommodation land use shows prominent effects on traffic. In the evening peak hour, shopping land use significantly impacts traffic. The study provides a basis for urban tourism land use adjustment to achieve the sustainable development of tourism traffic.

Wildfires in the Iberian Peninsula were large and frequent in the second half of the 20th century. Land use and land cover (LULC) also changed greatly. Our aim was to understand the relationship between LULC and fire in the western and eastern ends of the Iberian Central Mountain System. We compared two case study landscapes, the Estrela massif and the Ayllón massif, which are biophysically similar but with different social-ecological contexts. In both, fires were in general more likely in shrublands and pastures than in forests. Shrublands replaced forests after fires. Contrasting LULC in the two massifs, particularly pastures, likely explained the differences in fire occurrence, and reflected different regional land use policies and history. Fire here is a social-ecological system, influenced by specific LULC and with implications from landscape to regional scales. Understanding how LULC changes interact with fire is powerful for improving landscape and regional planning.

With the rise of the importance of air transportation in the 21st century, the role of economics in airport planning and decision-making has become crucial to the urban structure and land values. This paper examines the relationship between an airport and its impact on the distribution of urban land uses and land values by applying the Alonso’s bid-rent model. Using Suvarnabhumi International Airport as a case study, the analysis was made over three different time periods of airport development. The statistical results confirm that: (i) Alonso’s model can be used to explain the impacts of the airport only for the northeast quadrant of the airport; (ii) proximity to the airport shows an inverse relationship with the land value of all six types of land use activities through three periods of time; and (iii) the land value for commercial land use is the most sensitive to the location of the airport compared to other types of land use activities.

<p>We utilized satellite and GIS technologies to address the relationship between urban land uses and Noise Pollution (NP) in one of the most crowded regions of Tehran city. Leq was determined in 170 stations of the studied area and an acoustic map was created. Moreover, using satellite remote sensing data and a land use map, the density map for nine types of the most important urban land use was provided and the relationship between different land use densities and NP was investigated. We found that the investigated region was highly polluted and the NP level was higher in the morning (76.29±5.61 dB[A]) and afternoon (76.46±4.88 dB[A]) in comparison to the noon period. Furthermore, the prepared acoustic map revealed that in the east and southwest of the studied area, the NP was highest and lowest, respectively. Also, cultural (73.48±4.7 dB[A]) and parking (79.02±4.3 dB[A]) areas had the lowest and highest levels of Leq. Also, the high density of road, commercial, industrial, mixed commercial and residential and parking land uses had a direct significant relationship with Leq and this relation was inverse for green space. It was concluded that land use variations significantly affect the NP levels and it can be utilized to predict and manage the NP in different cities.</p>
