ABSTRACT
Recently the interest of public and stakeholders were focus on the
environmental status of Kuching Wetland National Park (KWNP) due to the increase
of urbanization processes and anthropogenic activities. A field sampling which
covered 10 stations was conducted at the outer and inner boundary of KWNP in
August 2011 during high tide. Physico-chemical water parameters were recorded.
Triplicate of near bottom water samples were collected using 2.5 L Van don
water sampler (Wildco®) for further analyses of nutrient, chlorophyll a (chl a), biological oxygen demand (BOD)
and total suspended solids (TSS). The aimed of the study were to assess
the water quality of KWNP and to determine the distribution pattern
of physico-chemical components and its relationship to the phytoplankton
chlorophyll a concentrations in
water between the outer and inner part of KWNP. One-way analyses of
similarity indicated that all the study sites were significantly different
between stations (p-value < 0.05) and boundaries (p-value
< 0.05). Water temperature, pH, ammonium nitrogen (NH4–N) and
inorganic phosphorous (Inorg–P) were known affecting the abundance of phytoplankton
communities. The concentrations of nitrate nitrogen (NO3–N) at the outer
and inner boundaries of KWNP were over-ranged as compared to Malaysia
marine standards.

ABSTRAK
Kebelakangan ini perhatian orang awam serta pihak berkepentingan
tertumpu kepada status alam sekitar di kawasan Taman Negara Tanah Bencah
Kuching (TNTBK)
disebabkan oleh peningkatan proses perbandaran dan aktiviti antropogenik di
kawasan tersebut. Kerja lapangan merangkumi 10 stesen telah dijalankan pada
waktu air pasang di bahagian luar dan dalam TNTBK pada 11 Ogos 2011.
Komponen fiziko-kimia air telah direkodkan. Tiga botol sampel air berdekatan
bahagian dasar telah diambil dengan menggunakan penyampel air Van don (Wildco®)
untuk analisis nutrien, klorofil a (chl a), permintaan oksigen biokimia (BOD) dan jumlah pepejal
terampai (TSS).
Tujuan kajian ini ialah untuk menilai kualiti air dan menentukan hubungan
antara corak taburan komponen fiziko-kimia air dengan kepekatan klorofil a fitoplankton pada bahagian luar dan
dalam TNTBK.
Analisis kesamaan satu hala menunjukkan bahawa terdapat perbezaan signifikan
(nilai-p<0.05) antara stesen bagi semua tempat kajian. Suhu
air, pH, ammonium nitrogen (NH4-N) dan fosforus bukan organik (Inorg-P)
didapati telah menjejaskan komuniti fitoplankton. Kepekatan nitrogen nitrat (NO3-N)
di sempadan luar dan dalam TNTBK didapati telah melebihi paras yang
dibenarkan oleh Piawai Marin Malaysia.
